A web page can be expired or not. When id does browser will try to fetch it from the server before displaying 'expired' message...
So basically you do not show 'expired' message at any time...
You may elaborate on what you try to do so we may help you with...

Mehdhi,
Not very clear but I guess this is what you are looking for

Add these lines in Pageload

C#

Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.Cache.SetExpires(DateTime.Now);

The above code will disable page cache,when back/Forward button is clicked,the current page will expire:)

This is true but I don't think it guarantees that the browser will show that message. Depending on IE settings, for example, IE may see it expired and just request it again and therefore the message will be shown.

+5 though since this is probably the best answer we can give based on the information provided.
