Solution 1

Write this code on the redirected page,

C#

Session["EmpId"] = null;
Session["EmpPwd"] = null;
//or
Session.Clear();
Session.Abandon();

Clear() - Removes all keys and values from the session-state collection.
Abandon() - Removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out.

Rather than setting the variable to null you're better using Session.Remove()

5ed; but as F-Es said, do not set them to null. Consider native functions to work with.
