When the user
hit the back button a locally cached copy of the previous page is retrieved
without notifying the server. As a result the Info is out of sync.
Solution
1 --> Disable caching (do not work for all browsers)
Code to disable caching (to be executed everytime thepage is loaded)
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(Now.AddSeconds(-1)); //--- (-1) means the page already expired
Response.Cache.SetNoStore();
//--tell the page not to cache the page
Response.AppendHeader("Pragma",
"no-cache"); //---adds a
header to the HTTP response object
Solution
2 --> Use timestamps or random numbers to track pages and detect when a page
is current
