WebDisp

TWebSession represents an active Web session. Use its Values property to get or set application-specific information about the current user. If your application uses sessions to store user information, you need to include a TSessionsService component in the Web application module. 

A Web session stores information that persists over multiple calls from the same user. This information is stored as a set of Variant values that are indexed by name. You can use these named Variants to store application-defined information that is associated with a single user.  

There is no need to instantiate session objects. A Session is created automatically when the WebSnap application receives an HTTP request message. The new session is given a unique identifier, which is added (in a cookie) to response messages, so that the same session can be used for subsequent requests from the same caller. The session persists until either the user logs out, a specified time elapses with no request messages from the caller, or the application explicitly calls the session's Terminate method.
