Hi,
I have the similar thing to b implemented.All the pages of the application are supposed to b expired.i had written the following code in global.asax.

protected void Application_BeginRequest(Object sender, EventArgs e)
{
// Fires at the beginning of each request
//this help you out in getting refreshed page always
Response.Buffer = true;
Response.Expires = -1000;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
Response.AddHeader("pragma", "no-cache");
Response.AddHeader("cache-control", "private");
Response.CacheControl = "no-cache";
}



try this.i hope it will give u the desired result.

Response.ExpiresAbsolute = DateTime.Now.AddDays(-1)
Response.AddHeader("pragma", "no-cache")
Response.AddHeader("cache-control", "private")

I take that back...I think the code is working..I am just not getting the page that displays "WARNING: PAGE EXPIRED"

Yea - that warning is displayed if you try to re-view a page that was the response from a POST request. Those are annoying. what you have now is that the page will always be refershed (another GET request issued by the browser) when you go back to it.
