So effectively you don't want the users to ever be able to leave?

They reloaded because of a redirect on the previous page. Double-clicking the back button usually fixes those. No magic involved there - it's actually normal behaviour on large sites that move pages from time to time.

The worst is MSDN.

You can try using the HttpResponse.Ca che property if that would help:

Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.SetValidUntilExpires(false);
Response.Cache.VaryByParams["Category"] = true;

if (Response.Cache.VaryByParams["Category"])
{
   //...
}

Or could could block caching of the page altogether with HttpResponse.Ca cheControl, but its been deprecated in favor of the Cache property above:

Response.CacheControl = "No-Cache";

Edit: OR you could really go nuts and do it all by hand:

Response.ClearHeaders();
Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1 
Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1 
Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1 
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1 
Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1 
Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1
