Decodes a URL-encoded session identifier obtained from a cookie or the URL.
Assembly: System.Web (in System.Web.dll)
This method is not intended to be called from application code.
This method is used internally by the SessionIDManager class to decode custom SessionID values created by classes that inherit the SessionIDManager class and override the CreateSessionID and Validate methods. To ensure the fidelity of a custom session-identifier value retrieved from the HTTP request by the GetSessionID method, the SessionIDManager decodes the custom value using the UrlDecode method.Notes to Inheritors
