Hi,

I can see what you mean - but most likly this is the problem with the user's
end browser, and not your app. As i am coming from PHP background, it was
allways concidered a good programming style to disable any catching done by
the browser / proxy server in HIGH security applications. What normally
happens when the user presses back button is that the last page is brought
up by the browser without even sending a request to server.

However this generally can be fixed by using HTPP headers "Cache-Control:
no-cache, must-revalidate" and "Pragma: no-cache". Since i'm only
begginging ASP.NET i cannot help u with the name of the function that
manages HTTP headers in .NET, but i can assure u that there is one. Also,
do read more on Cache-Control: and Pragma: HTTP headers (Google it)
