Creates a unique session identifier.
Assembly: System.Web (in System.Web.dll)
Return ValueType: System.String
A unique session identifier.
The method is used to generate a unique session identifier that the SessionStateModule object will use to identify a new session. The value returned by must be unique and must contain valid characters that can be stored in an HTTP response and request. If it is possible that the value returned by your implementation contains characters that are not valid in an HTTP response or request, you should use the UrlEncode method to encode the session-identifier value in your SaveSessionID method implementation and the UrlDecode method to decode the session-identifier value in your GetSessionID method implementation.
