facing problem in logout code in asp.net c#

Hi,

 

 If you are using forms-based authentication, ASP.NET having enough built-in methods by using it you can achieve your requirements.  

 

Once you log in, ASP.NET will create a session ID and keep it in the valid Cookie and pass that as a response to the client. From next request, a browser will send this cookie information to the server such that it will validate the session ID and activates respective session data on the server.

 

If you log out, your session data will be removed and it never regains again. 

 

You can get the practical code in below link
