Stateless and Session-based Processing
Regular HTTP servers are stateless processors: a user's browser may send several
sequential requests, but the HTTP server does not keep any information about the browser or
the client between the requests. Each request is processed individually.
The Web Application Server allows users to "log in", providing a name of some CommuniGate Pro
Account and the account password. For each successful login, a Session is started.
The session keeps the information about user actions and requests, so all HTTP requests sent to
the same session can share and use the same set of session data.
To maintain a session, all session requests have URLs in the following form:
- http://hostname:serverport/Session/sessionID/sessionRequest
where the sessionID string identifies the session, and the sessionRequest is the name of the
file to retrieve or the application component to run.
The Web Application Sessions have time-out counters. If no HTTP request has been sent to a session during
the configurable time-out interval, the Session is closed. The session user can close the session by
sending a request for the special Bye page.
Skins
The Server WebUser Interface implements Skins. Each Skin is a set of files that
define how the information is presented to users. Skins files include:
- WSSP files used to build "web pages" (HTML, WML, etc.) and format the page data.
- static service files - graphic elements, style sheets, etc.
- Language files containing various static text strings (messages, page and button titles, tags, etc.) referenced from WSSP files.
The CommuniGate Pro software comes with one Unnamed Stock Skin, providing the very basic and simple HTML interface.
It also comes with some Named Stock Skins that provide more visually rich interfaces.
This Stock Skins are stored in the application directory, they are parts of the software package,
and they should not be modified by server administrators.
CommuniGate Pro installations can also use Unnamed and Named custom Skins. Custom Skins can be created as Server-wide
Skins. These custom Skins are available to all users. Each CommuniGate Pro Domain can also
have its own set of custom Skins, available only to the users of that Domain.
When a user connects to the WebUser Interface service (the HTTP User port),
the hostname string specified in a stateless request URL is used to find the CommuniGate Pro
Domain. When the Domain is found, its Default Account WebUser Preferences are
retrieved and the SkinName (Layout) and Language Settings are used.
The SkinName Setting specified the name of the Skin to use (if that Setting is empty, the Unnamed Skin is used).
If the Skin with the specified Name is not found in the set of the Domain Skins, the Server-wide
Skin sets are checked. If the Skin with the specified name is still not found, the Stock Skin with this name is used.
If the Named Stock Skin is not found either, the Unnamed Stock Skin is used.
Since Domains can have their own Skin sets, the same request sent to different
Domains can display different pages: the Default WebUser Preferences can specified different Skin Names
in different Domains, and even if the Preferences are the same, different Skins
with the same name can exist in different Domains.
Stateless requests can use any Skin available for the addressed Domain. To use an alternative
Skin, a Stateless HTTP request should specify the Skin name using the Skin request parameter.
The Language Setting retrieved from the Domain effective Default Account WebUser Preferences
specifies the language to use on the stateless page. To use an alternative language,
a Stateless HTTP request should specify the language name using the Language request parameter.
Session-based HTTP requests do not use the hostname string specified in the URL.
Instead, when a user logs in, and a Web Application session is created for the specified
CommuniGate Pro Account, the effective Account WebUser preferences are retrieved.
Those preferences contain the name of the Skin to use (an empty value specifies an Unnamed Skin).
The Skin with the specified name is selected from the Skin set of the Account Domain
(note that the Domain specified with the request URL can be different).
If the Account Domain does not have the specified Skin, the Server-wide Skin is used.
Session-based HTTP requests use the Language specified with the Account WebUser Preferences.
Skin Files Hierarchy
When a WebUser Interface request is processed, the Server needs to retrieve certain files from the selected Skin.
If the requested file is not found in the selected Skin, and the selected Skin is a Domain Skin,
the file is retrieved from the Server-wide Skin with the same name.
If the requested file is not found in the Server-wide Skin, the Stock Skin with the same
name is checked. If the file is still not found, and the selected Skin is a Named Skin, then unnamed
Server-wide and unnamed Stock Skins are checked.
Initially, when no Domain has any custom Skin, and the Server-wide Skins are empty, all Domains
can use the Stock Skins only. The Unnamed Skin is selected by default.
By uploading files into the Server-wide Unnamed Skin, the Server Administrator can "shadow" the Unnamed Stock Skin files,
and this can change the application look and feel for all Domains.
By uploading files into the Unnamed Skin of some CommuniGate Pro Domain, the Server
or Domain Administrator can "shadow" the Stock Skin and Server-wide Unnamed Skin files and change the
look and feel for that particular Domain.
This hierarchy allows Server and Domain Administrators to use new Skins that are designed "from scratch",
or to develop small Skin variation, re-using the already existing Skins.
The Dynamic Cluster installations have two sets of the
Server-wide Skins - one set is used for local Server Domains, while the other, Cluster set is used for
all Shared Domains in the Cluster. Modifications of these Cluster-wide Skins, as well as
modifications of any Skin in any Shared Domain are automatically distributed to all Cluster Members.
Languages and Skin Text Dataset
Each Skin can have a Text Dataset - the strings.data text file.
This "default language" file contains a dictionary.
The WSSP script pages can use various commands to retrieve data from this Text Dataset dictionary.
A Skin can contain additional, localized Text Dataset files - language.data files,
where language is the language name (french.data, japanese.data, etc.). If a non-default
language is selected, the Text Dataset from the specified language file is used.
When the selected Text Dataset of the selected Skin does not contain the requested data,
the same language Text Datasets are checked in all Skin "parents" (as specified above).
If the requested data is still not found, the "default language" Text Dataset is used.
Use the UTF-8 character set to place non-ASCII symbols strings into a Text Dataset file.
Check the http://www.unicode.org
site to learn more about Unicode and the UTF-8 charset.
You may want to break one Text Dataset file into several files. You can place
several strings.subname.data files into a Skin.
These files are read when the strings.data file is read.
The file content (a dictionary) is added to the Text Dataset dictionary as the subname key value.
The language.subname.data files are processed in the same way, extending the
localized Text Datasets.
Serving Regular Files
When a URL specifies a file with any file name extension other than .wssp,
the Web Application module retrieves this file from the selected Skin, places it into the
internal Skin Cache, and returns that file to the client browser via the HTTP module connection.
The specified file names are always converted into the lowercase letters.
When the Web Application module receives a request for the same file, it is retrieved from the Skin Cache.
If the file has been requested using a Session-based URL, the session time-out counter is reset.
This can be used to create a frame in the client browser window, and make that frame periodically
retrieve some file using the session URL. As a result, this session inactivity timer can be reset
to keep the session alive as long as this frame is displayed in the user's browser.
System and Domain administrators can upload custom files into server-wide and Domain Skins to
modify the Web Application look and feel.
For example, the Stock Skin uses the Logo.gif file for most of its pages. By uploading
a custom Logo.gif file to a server-wide Unnamed Skin you can change the look of the Web Application
pages even without creating and uploading custom page (WSSP) files.
To include a file reference to into a .wssp page retrieved with a Stateless request, use
the %%filesRef%% prefix in the .wssp code:
... href="%%filesRef%%filename.extension" ...
See the Code Components for Stateless Requests section for more details.
Sessions can use Named Skins, and the session-based pages usually need to refer to
regular files in the same Skin. References in the "session realm"
( href="filename.extension" or href="/Session/sessionID/filename.extension")
work, but they do not allow client browsers to cache these files between sessions, since each session has
its own sessionID, and file URLs are different for each session. To allow client browsers to cache
regular files, use the %%SESSION(filesRef)%% prefix for file URLs:
... href="%%SESSION(filesRef)%%/filename.extension" ...
See the Session Dataset description for more details.
Serving Web Application (WSSP) Files
When a URL specifies a resource with the .wssp file name extension, the Web Application
module retrieves the specified WSSP file from the Skin, and Compiles it into some internal code.
The module then runs the Web Application code associated with the file name. This code produces
a dataset with various string, array, and dictionary data. Then the module runs the WSSP internal (compiled) code to
produce an HTML page using this dataset, and returns the resulting HTML page to the
browser using the HTTP module connection.
The specified resource names are always converted into the lowercase letters.
The WSSP Scripting section explains the WSSP file format. System and
Domain administrators can create custom WSSP files and upload them to the server-wide and Domain
Skins to modify the Web Application look and feel.
The section below lists the available Web Application code components,
defining the set of WSSP pages that this version of CommuniGate Pro server can generate. It specifies
how each component processes the form parameters sent to it, and what data is included into the
dataset it generates.
Creating and Managing Skins
You can create and manage Skins using the WebAdmin Interface,
CLI/API, or any client/protocol (such as FTP)
that can access the Account File Storage.
WebAdmin Editor
The WebAdmin Interface provides Skin Editor pages to manage Server-wide, Cluster-wide, and Domain Skins.
To manage the Server-wide and Cluster-wide Skins, open the Users realm of the WebAdmin Interface, and click the Skins link.
To manage the Domain Skins, open that Domain page in the Users realm of the WebAdmin Interface,
and click the Skins link. The Domain Administrator should have the CanModifySkins Access Right to be able
to create and modify the Domain Skins.
When the Domain Skins Editor page is opened, and there is no Unnamed Skin for
the Domain, the page contains the Create Unnamed Skin button. Click this button to create the Unnamed Skin for this Domain.
The Skin Editor page contains the list of all files "visible" in this Skin: it
lists files directly uploaded to this particular Skin, as well as all files uploaded
to the Skins used as the "default files" source for this Skin:
Files directly uploaded to the Skin have a checkbox in the Marker column. Files from the other skins "visible"
in this Skin have the word default in that column.
You can download any of the Skin files by clicking the file name.
You can upload a file to the Skin by clicking the Browse button and selecting a file on your workstation,
then clicking the Upload button.
You can delete any of the files uploaded to the Skin by selecting the checkboxes and clicking
the Delete Marked button.
If you are uploading a .wssp or a .wssi file, the Editor tries to compile that WSSP file first.
If you are uploading a .wcgp or a .wcgi file, the Editor tries to compile that CG/PL file first.
If you are uploading a .data file, the Editor tries to parse it as a dictionary file first.
If the compiler or the parser detects an error, the file is not uploaded, and the file content
is displayed on the Editor page, with the red <--ERROR--> marker
indicating the location of the error.
When you upload a file to any Skin, that Skin cache is automatically cleared. If you upload a file
to a Shared Domain Skin or to a Cluster-wide Skin, the update automatically propagates to all Cluster Members.
You can upload a set of files by uploading a TAR-archive (a file with .tar name extension). For example,
when you have a TAR-archive with a predesigned Skin you can open the Skin you want to modify (the
Server-wide Unnamed Skin or Domain-wide Unnamed Skin or some Named Skin), and upload the .tar file. The
Server will unpack the archive and store each file individually, as if they were uploaded one-by-one.
The Editor page for the Unnamed Skin contains the list of all Named Skins:
To create a Named Skin, enter its name, and click the Create button.
To remove Named Skins, use the checkboxes to select the Skins, and then click Remove Marked button.
Only empty Skins (Skins without any files) can be removed.
To remove the Unnamed Skin, remove all its files and all Named Skins, and then click Remove Unnamed Skin button.
To open a Skin, click its name. The Editor will display the Skin Name, and it will provide the UP
link to the Unnamed Skin page.
The Named Skin Editor allows you to rename the Skin by entering a new Skin Name and clicking the Rename Skin button.
CLI/API
The Command Line Interface/API can be used to manage Skins. See the Web Skins Administration section for the details.
Virtual File Storage Area
The Skins can be modified using FTP and HTTP clients, CG/PL applications, and any other
method that provides access to the Account File Storage.
Special $DomainSkins, $ServerSkins, and $ClusterSkins directories
provide access to the Domain and Server/Cluster-wide Skins.
Request Processing
The CommuniGate Pro Web Application module processes a request for a WSSP file by calling a
code component that produces a dataset - a dictionary
containing text string keys and values, associated with those keys. Values can be text strings, arrays of values,
or dictionaries.
For example, when a Domain default page is requested, the code component called and it produces
a dictionary that contains keys such as canAutoSignup, hasMailLists, hasCertificate.
The Web Application module then uses the script code from a WSSP file to convert this data into
into an HTML or other markup language page.
This section lists the available CommuniGate Pro code components, specifies when those components
are called, explains how the code components process the <FORM> parameters, and specifies the content
of the dataset produced by each code component.
Code Components for Stateless Requests
The Web Application module checks the Skin HTTP parameter for all Stateless requests.
If this parameter exists, the module tries to open a Named Skin with the specified name, otherwise
the Unnamed Skin (for the addressed Domain) is used.
The Web Application module checks the Language HTTP parameter for all Stateless requests.
If this parameter exists, the module uses it to selected a non-default Text DataSet for the selected Skin.
The Web Application module places certain data into datasets produced with all Stateless Requests code components.
The following list specifies these "generic" dataset elements that can be used with all Stateless WSSP pages:
- filesRef
- This element value is a string that can be used to form a URL that refers to a file (image, style sheet, data, etc.)
from the same Skin in the same Domain. The <img src="%%filesRef%%Logo.jpeg"> HTML
element will display the Logo.jpg file "visible" in the current Skin.
- serverName
- This element value is a string with this CommuniGate Pro server name (its Main Domain Name).
- skinName
- This optional element value is the current Skin name string.
- language
- If a non-default language was selected, this optional element contains a string - the selected language name.
- domainName
- This element value is a string containing the CommuniGate Pro Domain name.
This element exists only if the Server has succeeded to direct the Stateless Request to one
of the server Domains.
- accessURL
- This element value is a string containing the preferred URL to access the domain's Web services.
This element exists only if the Server has succeeded to direct the Stateless Request to one
of the server Domains.
- charset
- This element value is the value of the charset element from the Domain Skin Text Dataset. Individual code
components may specify other values for the charset element (see below).
- secureChannel
- This element exists and has the YES string value if the request has been received via a secure (HTTPS) connection.
The following sections specify the Stateless URLs, the name of the code component called, the actions
taken by the component, the dataset produced with that component, and the name of the WSSP file used to produce the HTTP response.
URLs: /, /default.html
these URLs are used to process Login operations.
- Actions
-
If the HTTP request has the username and password parameters, the code
tries to authenticate the client using these parameter values. If the supplied
credentials are correct, a new WebUser Session is
created, and a request for the "entry page" is sent to the Session. This request usually
returns an HTML "jump page" that is sent back to the user browser. It forces the browser to
enter the "Session realm".
If the request has the DisableIPWatch parameter, the "Fixed IP Address" security
feature will be disabled for this session, even if the Account WebUser preferences enable it.
If the request has the DisableUseCookie parameter, the "Use Cookies" security feature
will be disabled for this session, even if the Account WebUser preferences enable it.
If the request has SessionSkin parameter with a string value not equal to *,
the session is opened using the Skin specified with this parameter. The Skin is searched in the
Domain of the logged-in user (which can be different than the Domain used to display the Login page).
- Result Dataset
- If username or password parameter has not been specified, or a
WebUser Session could not be created, the component generates the following dataset:
- autoSignup
- this element (with the string YES as the value) is added to the dataset
if the addressed Domain provides the Auto-Signup operation.
- clientAddress
- this string element contains the IP address of the user browser.
- errorCode
- this element is added to the dataset if the Login operation has failed. The value is a string with the error code.
- forgotPassword
- this element (with the string YES as the value) is added to the dataset
if the errorCode value is "Incorrect Password" or "Unknown Account".
- hasCertificate
- this element (with the string YES as the value) is added to the dataset
if the addressed Domain has a custom Certificate.
- hasDirectory
- this element (with the string YES as the value) is added to the dataset
if the default Skin for the addressed Domain has an array element GuestDirectoryFields in
its Text Dataset, and that array is not empty.
- hasLists
- this element (with the string YES as the value) is added to the dataset
if the addressed Domain has at least one Mailing List. This element is always added if the
addressed Domain is a Shared Domain.
- skinNames
- this element contains an array - the list of skin names available in the addressed Domain.
- loginName
- this string element is added to the dataset if the user has tried to log in, but failed.
The value specified in the username parameter becomes the loginName element value.
- restoreSessionPage
- this string element is added to the dataset if the user has been disconnected.
It contains the name of the interrupted request session page name.
To allow an interrupted request to resume, the restoreSessionPage HTTP parameter with this
element value should be included into the HTTP request generated by this page.
- restoreCharset
- this string element is added to the dataset if the user has been disconnected.
It contains the charset used in the interrupted request.
To allow an interrupted request to resume, the restoreCharset HTTP parameter with this
element value should be included into the HTTP request generated by this page.
- restoreParameters
- this array element is added to the dataset if the user has been disconnected.
Each array element is a dictionary with the following elements:
- name
- name of an interrupted request parameter.
- value
- encoded value of an interrupted request parameter.
To allow an interrupted request to resume, parameters with these names and values should be
included into the HTTP request generated by this page.
- WSSP page
- the login.wssp page is used to generate the HTTP response.
If login operation was successful, the HTTP Redirect response is returned, with
the Redirect URL pointing to the StartPage wssp page within a newly created Session.
The StartPage is specified as the StartPage Skin string.
If login operation was successful, but the request contained the restoreSessionPage
parameter, the resume.wssp page is displayed (as a Stateless one).
The Result Dataset for this page contains:
- restoreParameters
- see description above.
- sessionID
- the SessionID for the newly created session (the same value as the value of SESSION(ID) function that can be used on session wssp pages).
- jumpPage
- the wssp page to open if the user wants to resume the interrupted operation (it includes optional parameters).
URL: /RecoveryPassword.wssp
this URL is used to process Password Recovery operations.
- Actions
- If the HTTP request has the username and Send parameters, the
component tries to find the specified Account, retrieves the Account password, and
the RecoverPassword Account Setting. If the password can be decrypted and the
RecoverPassword is specified, an E-mail message containing the password is composed and
sent to the RecoverPassword E-mail address.
- Result Dataset
-
- errorCode
- this element is added to the dataset if the Password Recovery operation has failed.
The value is a string with the error code.
- messageCode
- this element is added to the dataset if the Password Recovery operation has succeeded.
The value is the PasswordSent string.
- WSSP page
- the recoverypassword.wssp page is used to generate the HTTP response.
URL: /Signup.wssp
this URL is used to process Auto-Signup operations.
- Actions
- If the HTTP request has the username, password1, password2,
and the realName parameters, the component tries to create the specified Account.
Before it tries to create an Account, it checks if the password1 and password2
strings are the same. If a new Account is created, its UseAppPassword setting is set
to YES, the Password and RealName settings are
set to the specified values. If the HTTP request contains a non-empty ForgotPassword parameter,
it is used as the RecoverPassword Account Setting.
The component checks if the request contains one or more PublicInfo string parameters.
The value of the parameter must be one of the Public Info Attributes specified in the
Directory Integration settings. The component than checks if
there is a non-empty request parameter with this name, and adds the parameter value to the
initial Account settings.
Example: to provide a City field on the Auto-Signup
page, include the <INPUT type="hidden" name="PublicInfo" value="City"> control
and the <INPUT type="text" name="City" value="" size=30 maxlength=255> control into
the Signup.wssp HTML code.
If an Account has been created, a new WebUser Session is created, and a request for the "entry page" is sent to the Session
(see above).
- Result Dataset
-
If username, password1, password2,
or the realName parameter has not been specified in the HTTP request, or a new Account
could not be created, the component generates the following dataset:
- errorCode
- this element is added to the dataset if the Auto-Signup operation has failed.
The value is a string with the error code.
- userName
- this element is added to the dataset if HTTP request contained a non-empty userName parameter.
The element value is the value of the parameter.
- realName
- this element is added to the dataset if HTTP request contained a non-empty realName parameter.
The element value is the value of the parameter.
- recoverPassword
- this element is added to the dataset if HTTP request contained a non-empty recoverPassword parameter.
The element value is the value of the parameter.
- WSSP page
- the signup.wssp page is used to generate the HTTP response.
URL: /List/, /List/default.html
this URL is used to retrieve the list of the browsable Domain Mailing Lists.
- Actions
- The HTTP request parameters are not processed.
- Result Dataset
-
The component generates the following dataset:
- errorCode
- this element is added to the dataset if the list retrieval operation has failed.
The value is a string with the error code.
- lists
- this element contains an array of mailing list descriptors. Each descriptor is a dictionary with
the following keys and values:
- name
- a string with the mailing list name.
- realName
- the mailing list "description" string.
- browse
- the string describing the mailing list archive browsing policies. The string value can be anyone or subscribers.
- WSSP page
- the listlist.wssp page is used to generate the HTTP response.
URL: /List/listname/, /List/listname/List.html
this URL is used to retrieve a portion of the mailing list records for the listname Mailing List.
The code component actually uses the generic Mailbox Code Component.
- Actions
- The component checks if the HTTP request contains the NextMessage parameter with a numeric value.
If it exists, the value is interpreted as the unique message ID (UID) in the list archive Mailbox, and the component
tries to find this message in the selected Mailbox "view", and tries to find the next message in the view.
The component checks if the HTTP request contains the PrevMessage parameter with a numeric value.
If it exists, the value is interpreted as the unique message ID in the list archive Mailbox, and the component
tries to find this message in the selected Mailbox "view", and tries to find the previous message in the view.
If the next or previous message is found, its UID is added to the dataset (see below) and the generic Mailbox component
is not used for processing.
If no next/previous message is found, the generic Mailbox component is used to process the HTTP request parameters
and to compose the resulting dataset.
- Result Dataset
-
- listName
- a string with the Mailing List name.
If a next or previous message is found:
- messageJump
- a string with the found message UID.
If a next or previous message was not requested in the HTTP request parameters or it was not found:
- realName
- the Mailing List Description string
- charset
- the Mailing List Preferred charset string
the generic Mailbox code component is used to generate the rest of the resulting dataset.
- WSSP page
- the listmailbox.wssp page is used to generate the HTTP response.
URL: /List/listname/Message/uid.html
this URL is used to retrieve the message with uid unique ID from the listname mailing list archive.
The code component actually uses the generic Message Code Component.
- Actions
- The generic Message component is used to process the HTTP request parameters
and to compose the resulting dataset.
- Result Dataset
-
- listName
- a string with the Mailing List name.
- nextMsg
- this element is added if there is a next message in the archive Mailbox view. The element value
is a string with the next message UID.
- prevMsg
- this element is added if there is a previous message in the archive Mailbox view. The element value
is a string with the previous message UID.
The generic Message code component is used to generate the rest of the resulting dataset.
- WSSP page
- the listmessage.wssp page is used to generate the HTTP response.
Error Pages
The WSSP mechanism is used to generate HTTP response body for error responses. The following table
lists the HTTP error codes, the situations when this error code is generated, and the WSSP file
used to product the HTTP error response body.
| Code | Error conditions | WSSP file used |
|---|
| 301 | the requested resource has been moved | moved.wssp |
| 404 | the requested resource does not exist | notfound.wssp |
| 401 | the requested page requires the HTTP Authorization (request header) | unauthorized.wssp |
| 401 | the credentials in the HTTP Authorization request header are incorrect | denied.wssp |
| 500 | generic system error | failure.wssp |
| 501 | generic system error | error.wssp |
|
These WSSP pages are processed using datasets generated for all Stateless requests, with
the following additional elements:
- errorCode
- this element is added to the dataset if there is an error code to be reported to the user.
- hostName
- this element is added to the dataset if the HTTP request contained the Host: field. The
element value is that request field parameter.
The disconnected.wssp page is used when an HTTP request was sent to a WebUser Session,
but the session has not been found. The page is processed using a dataset generated for all Stateless requests.
Code Components for Session Requests
When a new WebUser Session is created, the Skin specified in the Account WebUser Preferences
is opened and is used as the "Session Skin". The string StartPage is retrieved from
that Skin Text Dataset, and a jump page is composed and sent to the user browser. The jump page
redirects the user browser into the "Session Realm", to the page specified with the StartPage string.
HTTP requests to the "Session realm" (requests with URLs started with /Session/)
are processed as Session Requests. The second component of the Session Request URL is a unique Session ID, the HTTP module
uses it to find the WebUser session.
If the specified session is not found, or the Session has the Fixed Network Address option set,
and the HTTP request did not come from the same IP address as the Login request that started the session,
the disconnected.wssp page is displayed (see above).
After the Session is found, the Web Application module processes the rest of the request URL
as the "request inside this session realm". If the request URL specifies a regular file, that
file is retrieved from the Session Skin, and it is sent back to the user browser.
For each .wssp request a code component is called. It processes the HTTP
request parameters and generates a result dataset. Then the .wssp file is retrieved from the Skin,
and it is used to compose the HTTP response.
If the result dataset does not contain the blockAlerts element, the Web Application
module checks if there is a pending Alert for the session user. If one or
several pending alerts are found, the Alerts code component is called, and the
Alerts.wssp file is used to compose the HTTP response.
The Web Application module checks for certain HTTP request parameters and processes them for
all .wssp page requests. The following list specifies these "generic" actions:
- EmptyTrashNow
- If the HTTP request contains this parameter, and the Mailbox or Mailbox
alias with the name Trash can be opened with the "Can Delete" Mailbox Access Right, then the code
component removes all messages from that Mailbox. If this operation
fails, the error code is placed into the resulting dataset as the errorCode string element.
- SMIMEUnlock
- If the HTTP request contains this parameter and the session does not have an Active Private Key, and the encrypted
Private Key exists in the Account Settings, and the HTTP request contains the SMIMEPassword parameter, the module
tries to activate ("unlock") the Private Key using the supplied password. If the operation fails, the error code is placed
into the resulting dataset as the SMIMEError string element.
The Web Application module places certain data into datasets produced with all Session Requests code components.
The following list specifies these "generic" dataset elements that can be used with all Session WSSP pages:
- messageText
- This string element is added if the HTTP request contains the messageText parameter. The element value is
the same as the HTTP parameter value.
- messageCode
- This string element is added if the HTTP request contains the messageCode parameter. The element value is
the same as the HTTP parameter value.
- secureChannel
- This element exists and has the YES string value if the request has been received via a secure (HTTPS) connection.
- charset
- This string element contains the Preferred Charset selected in the User Preferences, if the Use UTF8 mode is set
to Never. Otherwise, this element contains the utf-8 string.
Note: it's just a default value, individual code components can specify different values
for this dataset element.
- SMIMEActive
- This element exists and has the YES string value if the session has an unlocked (Active) SMIME Private Key.
- SMIMEInactive
- This element exists and has the YES string value if the session does not have an unlocked (Active) SMIME Private Key,
but the user has the Private Key in the Account Settings, and the Key can be unlocked.
- mailboxes
- The list of all selectable Mailboxes visible to the user.
If a .wssp request specifies an unknown code component,
but the .wssp file with the specified name can be retrieved from the Session Skin, that .wssp file
is processed using the dataset with the "generic" elements only, and the result is sent back to the
user browser.
- Example: The Stock Skin uses Hello.wssp requests. There is no code component with
this name, so a dataset with the generic values is composed, and the Hello.wssp file is
used to process this dataset.
The following sections specify the names of existing code components (names for .wssp requests),
the actions taken by these component, and the dataset produced with these components.
The code component results are processed using the .wssp files with the same names as the
code component names.
Name: Mailboxes
Actions
If the HTTP request contains the Create parameter and the NewName parameter is a non-empty
string, the component tries to create a Mailbox with the specified name. If this operation fails,
the errorCode element with the error code text is added to the result dataset. If the Mailbox
is created, the messageCode element with MailboxCreated string value is added to
the result dataset, and the created Mailbox name is added to the list of subscribed Mailboxes, if the
Show Subscribed Mailboxes option is selected in the Account WebUser Preferences.
If the request contains the newClass parameter, then the created Mailbox is set to the specified class.
If the HTTP request contains the Filter parameter, only the Mailboxes
with names containing this parameter value are included into the list.
Result Dataset
The code component creates a list of all Account Mailboxes and Mailbox Aliases (if the
Show All Account Mailboxes option is selected in the Account WebUser Preferences), or
the list of all subscribed Mailboxes (if the
Show Subscribed Mailboxes option is selected). If both options are selected, these two lists
are merged into one.

Name: Mailbox
The HTTP request must contain the Mailbox parameter - the name of the Mailbox to be displayed.
Actions
For each Mailbox, the module creates a session object that contains the Mailbox view
parameters. When the object is created, these parameters are initiated with the WebUser Preferences values.
The HTTP request Msg parameters are interpreted as "message set elements". A request can contain
several parameters, and each parameter should have a numeric value - the Unique ID of a Mailbox message.
If the HTTP request contains the Forward or Redirect parameter and the RedirectAddresses
parameter is not empty, a "message set" is composed using the Msg parameters, and the message set messages are
forwarded or redirected to the specified addresses.
If the HTTP request contains the ListApprove parameter and the Mailbox is an "approval" or "requests" Mailbox for some mailing list,
the request is processed as the Redirect request with the effective address being the mailing list address or the "subscription" request for that list.
If the operation has been successful,
the messageCode element with the MessagesForwardedInfo or MessagesRedirectedInfo string value
is added to the result dataset. Otherwise, the errorCode element with the operation
error code string value is added to the result dataset.
If the HTTP request contains the Copy or Move parameter and the MailboxName
parameter contains a name of some selectable Mailbox, a "message set" is composed using the Msg parameters,
and the message set messages are copied to the specified Mailbox. If the Move parameter was
specified, the message set messages are marked as Deleted, physically deleted, or moved to Trash - depending on the
WebUser Preferences.
If the operation has been successful,
the messageCode element with the MessagesCopiedInfo string value
is added to the result dataset. Otherwise, the errorCode element with the operation
error code string value is added to the result dataset.
If the WebUser Preferences DeleteMethod option is set to Move To Trash, and
the HTTP request contains the Delete parameter, a "message set" is composed using the Msg parameters,
the message set messages are copied to the Trash Mailbox and deleted. If the Trash Mailbox
did not exist, it is created.
If the HTTP request contains the DeleteAll parameter, all Mailbox messages are deleted, using the
method specified with the WebUser Preferences DeleteMethod option.
If the HTTP request contains the read, unread, flag, unflag, delete, or undelete
parameters, a "message set" is composed using the Msg parameters, and
the flags for the message set messages are modified. The delete and undelete parameters
are processed in this way only if the WebUser Preferences DeleteMethod option is not set to Move To Trash.
If the operation has not been successful, the errorCode element with the operation
error code string value is added to the result dataset.
If the WebUser Preferences DeleteMethod option is not set to Move To Trash, and
the HTTP request contains the Purge parameter, all Mailbox messages with the Deleted
flag are deleted.
If the operation has not been successful, the errorCode element with the operation
error code string value is added to the result dataset.
If the HTTP request contains the NextMessage parameter with a numeric value, the value
is interpreted as the unique ID (UID) of a Mailbox message, and the component tries to find the next Mailbox message.
If such a message is found, its UID is added to the Result Dataset as the messageJump element.
If the HTTP request contains the PrevMessage parameter with a numeric value, the value
is interpreted as the UID of a Mailbox message, and the component tries to find the previous Mailbox message.
If such a message is found, its UID is added to the Result Dataset as the messageJump element.
If the HTTP request contains the NextUnread parameter and the Mailbox contains an unread
message, the UID of that unread message is added to the Result Dataset as the messageJump element.
If the messageJump element was not added to the Result Dataset, the code component uses the
generic Mailbox component to process the HTTP request parameters and to compose the resulting dataset.
Result Dataset
- mailbox
- a string with the Mailbox name.
- mailboxClass
- if this string element exists, it contains the Mailbox class.
- mailboxPage

The generic Mailbox code component is used to generate the rest of the resulting dataset.
Name: Contacts
Processed in the same way as the Mailbox page.
Name: Notes
Processed in the same way as the Mailbox page.
Name: Calendar
The HTTP request must contain the Mailbox parameter - the name of a Calendar-type Mailbox to be displayed.
Actions
For each Mailbox, the module creates a session object that contains the Mailbox view
parameters. When the object is created, these parameters are initiated with the WebUser Preferences
values. The object also contains the month number for the "monthly calendar" view. It is initially set to the current month.
The object contains the day number that specifies the first day to be displayed in the Calendar view.
The object also contains the "byDay" flag that controls how the calendar data is stored in the dataset (by days or by time intervals).
The HTTP request prevMonthlyCalendar parameter can specify the number of months to be subtracted
from the "monthly calendar" month number.
The HTTP request nextMonthlyCalendar parameter can specify the number of months to be added
to the "monthly calendar" month number.
The HTTP request JumpDay parameter can specify the "day number in the epoch" that will become the first day
to be displayed in the Calendar view.
The HTTP request byDay parameter can specify the new byDay flag value.
The HTTP request Msg parameters are interpreted as "message set elements". A request can contain
several parameters, and each parameter should have a numeric value - the Unique ID of a Mailbox message.
If the WebUser Preferences DeleteMethod option is set to Move To Trash, and
the HTTP request contains the Delete parameter, a "message set" is composed using the Msg parameters,
the message set messages are copied to the Trash Mailbox and deleted. If the Trash Mailbox
did not exist, it is created.
If the HTTP request contains the read, unread, flag, unflag, delete, or undelete
parameters, a "message set" is composed using the Msg parameters, and
the flags for the message set messages are modified. The delete and undelete parameters
are processed in this way only if the WebUser Preferences DeleteMethod option is not set to Move To Trash.
If the operation has not been successful, the errorCode element with the operation
error code string value is added to the result dataset.
If the WebUser Preferences DeleteMethod option is not set to Move To Trash, and
the HTTP request contains the Purge parameter, all Mailbox messages with the Deleted
flag are deleted.
If the operation has not been successful, the errorCode element with the operation
error code string value is added to the result dataset.

the encoded URL for that other page is placed into this string element.
Name: Subscription
- Actions
-
If the HTTP request contains the Open parameter, the MailboxName parameter value
is converted into the "UTF-7 Mailbox Name encoding" format, the converted string is
added to the result dataset as the jump element, and the request processing ends.
If the HTTP request contains the Update parameter:
- All Elem request parameters are retrieved, converted into the "UTF-7 Mailbox Name encoding" format,
and form the new Account Subscription list.
- All AliasName request are retrieved, they should contain numeric values. For each
retrieved numeric value nnn, the parameters pairs annn and mnnn
are retrieved. If both parameters exist and contain non-empty strings, the strings are converted into
the "UTF-7 Mailbox Name encoding" format, and are used to form the new set of Account Mailbox Aliases.
- If the Subscription or Mailbox Aliases update operation fails, the errorCode element is
added to the result dataset. Otherwise the messageCode element with the Updated string value
is added to the result dataset.
- Result Dataset
-
- jump
- The name of the Mailbox to open ("to jump to"). If this element exists, none of the following
elements is added to the result dataset.
- subscription
- This array element contains the Account subscription list. Each array element is a string
with some Mailbox name.
- aliases
- This array element contains the Account Mailbox Aliases list. Each array element is a dictionary
with the following elements:
- index
- A string with this Mailbox Alias element index.
- name
- A string with the Mailbox Alias name.
- ref
- A string with the name of the Mailbox this Alias points to.
Name: Password
- Actions
- If the HTTP request contains the ModifyPassword parameter, the request should also
contain the OldPassword parameter, and that parameter should match the current Account
password. If the OldPassword parameter value is correct:
- The RecoverPassword request parameter value is set as the new RecoverPassword
Account setting. The messageCode element with the Updated string value is added to the result dataset.
- If the Account user is allowed to modify the Account password, the NewPassword1 and
NewPassword2 parameters are checked. If they are non-empty and match each other, then
the Account password is updated using these parameters value.
If the password has been updated successfully, the messageCode element with the PasswordChanged string value is added to the result dataset.
If the password update operation failed, the errorCode element is added to the result dataset.
- Result Dataset
-
- RecoverPassword
- This string element contains the Account RecoverPassword setting value.
Name: PublicInfo
- Actions
-
If the HTTP request contains the Update parameter, the request should also
contain zero, one, or several ID parameters, each with a numeric value. For each ID parameter,
its numeric value nnn is used to retrieve the pair of Nnnn and Vnnn string parameters.
The value of the Nnnn parameter specifies the name of the Account Public Info setting, the
value of the Vnnn parameter specifies the setting value. These pairs are used to set the new
Account Public Info settings. If an empty string is specified as a setting value, the setting is removed from
the Account Settings.
If the Public Info settings have been updated successfully, the messageCode element with the Updated string value is added to the result dataset.
If the password update operation failed, the errorCode element is added to the result dataset.

Name: Bye
- Actions
- The code component can delete old messages from the Trash (as specified in the WebUser preferences
and if string parameter noEmpty was not set)
and closes the session. The session will be destroyed as soon as this HTTP request is processed, so
the bye.wssp code can use session data, but the produced HTML code should not
contain references to session objects.

If the HTTP request contains the parameter Next, then the current first message index
is increased by the current Limit value.
If the HTTP request contains the parameter Prev, then the current first message index
is decreased by the current Limit value.
If the HTTP request contains the parameter Sort, its numeric value specifies the number
of "sorting" column (to sort the Mailbox view by the first column, the Sort parameter should be 0).

Generic Message component
The generic Message component is used to convert the an RFC822 message into
an HTML text. It processes simple and multi-part messages, attachments, digests,
inline images and other letter components. To build a HTML presentation,
the component uses Code Components for Message Rendering.
Code Components for Message Rendering
The Web Application module can render messages, converting them into a markup (HTML) text.
This process is controlled by the Application module itself. It detects the MIME structure of the
message, and processes each part recursively. For each part, a dataset is produced and a .wssp file is
used to produce a markup language presentation.
Message Rendering code components do not perform any actions.
A Result Dataset produced by every Message Rendering code component includes the following fields:
- MIMEPart
- this string element contains a URL reference for the message or the message part that is being rendered.
- filesRef
- this string element contains the URL prefix needed to retrieve files from the proper Skin. When a message
is being rendered withing some WebUser Session, this string is the same as the SESSION(filesRef) string.
- printVersion
- this string element exists and contains the YES string if the message should be
displayed in a printable form.
The following Message Rendering code components are implemented:

Redirect-type Response
Session and Stateless requests processed using WSSP files produce markup language documents.
Before these documents are sent to the client browser, their first lines are checked.
If the first document line starts with the <REDIRECT> tag, the rest of the document first line is interpreted as a URL.
The Server returns the 301 ("Moved") response code with the Location header containing the specified URL.
The Server also processes the <RELREDIRECT> tag at the beginning of the document. It is processed
in the same way as the <REDIRECT> tag, but the URL placed into the Location header is prefixed with the
http or https prefix, the server name (and, optionally, port number) retrieved from the request URL.
CG/PL Applications
Session and Stateless requests can be processed using CG/PL applications (rather than the code components built into the Server).
These CG/PL applications are called Web Applications.
A stateless request addressing a /programName.wcgp or /programName.wcgp/some_url resource makes the Server load the
programname.wcgp CG/PL application from the selected Skin.
If the application produces any output, it is returned to the client browser, otherwise the 404 Not Found error is returned.
An application can be started by addressing a /auth/programName.wcgp or /auth/programName.wcgp/some_url resource.
Such an HTTP request is authenticated first, and the application is executed on behalf of the authenticated Account.
An application can be started by addressing the /sys/programName.wcgp resource.
The application is executed in the Server-wide or the Cluster-wide Unnamed Skin environment on behalf of the
postmaster Account in the Main Domain. The sysEntry code section of the programName.wcgp file is executed.
Session requests addressing a /programName.wcgp in the Session (/Session/sessionID/) realm
makes the Server load the programname.wcgp CG/PL application from the Session Skin.
Only the GET, POST, and HEAD HTTP requests are supported.
If the application produces any output, it is returned to the client browser, otherwise the 404 Not Found error is returned.
The application is executed on behalf of the Account the Session belongs to.
When a CG/PL module is loaded to process an HTTP request, the main module entry is executed.
Web Applications can use CG/PL external-declarations.
When a code section (a procedure or a function) declared as external is called,
a file with the code section name and the .wcgi extension is loaded from the current Skin.
The program code in this file must contain the code section with the specified name and of the proper type (a procedure or a function).
The program code in an .wcgi file may contain other code sections as well.
CG/PL Web Applications can use the following built-in procedures and functions.
HTTP Request Input
- GetHTTPParameter(name [ ,index ])
- This function retrieves an HTTP request parameter. HTTP request parameters include URL parameters and/or form fields.
The name value should be a string specifying the HTTP request parameter name.
An HTTP request can contain several parameters with the same name.
If the index parameter is present, its value should be a number specifying which HTTP request parameter of the specified name should be retrieved.
If the HTTP request contains the FormCharset parameter, its value is interpreted as the character set name.
The function converts the raw parameter data into the UTF-8 character set. If the FormCharset parameter is absent,
the raw parameter data is assumed to be encoded using the UTF-8 character set.
If the parameter value contains several lines, the EOL (line separator) symbols are converted to those used with the Server host OS.
This function returns a string containing the parameter value.
If the parameter with the specified name and, optionally, index is not found, this function returns a null-value.
- GetHTTPBinaryParameter(name [ ,index ])
- This function retrieves an HTTP request parameter raw data.
This function returns a datablock containing the parameter value.
If the parameter with the specified name and, optionally, index is not found, this function returns a null-value.
- GetHTTPField(name)
- This function retrieves the name HTTP request field.
The following fields are supported:
Authorization, Referer, Destination, Cookie, User-Agent, Host.
If the name value is an empty string, the HTTP request URL (without the optional URL parameters) is returned.
If the name value is the Schema string, the request URL schema used (the http or https string) is returned.
If the name value is the Host string, the request Host field is returned, with the optional "port" part removed.
If the name value is the Port string, the port number from the Host field is returned; if no port is specified in that field, the number 80 is returned for clear text connections, and the number 443 for secure connections.
If the specified field name if not in the supported set, or if the request does not contain the specified field, this function returns a null-value.
- GetHTTPQuery()
- This function retrieves the parameter string from the HTTP request URL.
If the request URL does not contain parameters, the function return a null-value.
- GetHTTPResource()
- This function retrieves the HTTP request query string, including all URL parameters.
- GetHTTPMethod()
- This function retrieves the HTTP request method string (GET, POST, etc.).
- GetHTTPType()
- This function retrieves the HTTP request body Content type.
- GetHTTPSubtype()
- This function retrieves the HTTP request body Content subtype.
- GetHTTPData()
- This function retrieves the HTTP request body.
If the request body content subtype is xml or it ends with +xml, the function tries to convert the body content into XML and returns an XML object.
If the request body content type is text, the function converts the body content into UTF-8 and returns a string.
Otherwise, the function returns a datablock.
If any conversion operation fails, or if the request body is absent or it is too long, the function return a null-value.
HTTP Response Output
- SetHTTPResponseData(data)
- This procedure sets the HTTP response body.
The data value should be either a string, a datablock, a dictionary, or an XML object.
- SetHTTPResponseType(mimeType,subtype)
- This procedure sets the HTTP response Content-Type field values.
The mimeType and subtype values should be strings containing valid MIME atoms.
- SetHTTPResponseCode(code)
- This procedure sets the HTTP response code.
The code value should be a number in the 200..999 range or a string.
If the string starts with a 3-digit prefix and the - symbol, then the prefix
specifies the HTTP response code, and the rest of the string specifies the HTTP response text.
If there is no such prefix in the code string value, then the HTTP response code
is set to 500, and the entire string is used as the HTTP response text.
- RemoteIPAddress()
- This function returns an ip-address object specifying the IP Address the HTTP request was received from.
- ProxiedIPAddress()
- If the HTTP request was relayed by some external HTTP proxy, this function returns the original
client IP Address. Otherwise the function returns a null-object.
- SendHTTPContinue()
- This function sends the 100-Continue HTTP response.
If the response is successfully sent, the function returns a null-value, otherwise it returns an error code string.
- AddHTTPResponseField(fieldName,fieldValue)
- This procedure adds a field to the HTTP response.
The fieldName and fieldValue values should be strings.
- ProcessWSSP(pageName,resultSet)
- This procedure composes the HTTP response body using the specified WSSP page and the result dataset.
The pageName value should be a string with the page name (without the wssp suffix).
This page is retrieved from the currently selected Skin.
The resultSet value should be a dictionary.
The Server modifies this dictionary adding the common Session or stateless processing elements (see above),
and then it is passed to the WSSP interpreter.
The resulting page is set as the HTTP response body.
Session Data
Functions and procedures listed in this section are available only for Session HTTP requests.
- SessionData()
- This function returns the Session Dataset dictionary.
- SetSessionData(keyValue, keyName)
- This function updates the Session Dataset dictionary.
The keyName value should be a string, the keyValue value specifies the new object for that key. If the keyValue is a null-value, the object is removed from the Session Dataset dictionary.
