Page is accessible even after user has logged out

The page you see is browser cached page

To avoid caching add the following line to page load of all pages

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Sir,

I tried this.. Its still not working.

Hi..

Use Sessions to avoid the problem

to bind the data to sessions as Session["DynamicCon"] = mDynamicCon;

and session default time will be 20sec..u can also extend the time.

to retrive the session data as..

mcon = session["DynamicCon"].ToString();

after completion of your task, if u want to exit the respected form..at the time simply close all active sessions per page.

by 

Session.Abandon();

Session.RemoveAll();

if (Session["mOrgCode"] == null) { Session.Abandon(); Session.RemoveAll(); Response.Write("<script>window.alert('Your Session has been expired,Please Login again.')</script>"); Response.Redirect("NewLogin.aspx"); } else { mcon = new SqlConnection(Session["DynamicCon"].ToString()); }

Actually this should work there has to be some mistake from your side. i.e. you are not clearning sessions properly.

Use Session.Abandon(); to clear session

I have used

 Session.Abandon();         Session.Clear();
