How to Generate a new Session ID

You can do this using the SessionIdManager class:

SessionIDManager manager = new SessionIDManager();string newID = manager.CreateSessionID(Context);bool redirected = false;bool isAdded = false;manager.SaveSessionID(Context, newID, out redirected, out isAdded);

[Code sample is from Anas Ghanem's article]

you can use

SessionIDManager.CreateSessionID Method : returns a unique session identifier that is a randomly generated number encoded into a 24-character string.

Code

SessionIDManager Manager = new SessionIDManager(); string NewID = Manager.CreateSessionID(Context); string OldID = Context.Session.SessionID;bool redirected = false;bool IsAdded = false;Manager.SaveSessionID(Context, NewID,out redirected, out IsAdded);
