page expire

[pmmbala]

hi friends,
how can i make a page unavailable when someone hits their back button?

i am using these sts.. but some pages wont work..
Response.Expires = -1
Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache"

Thanks
Bala

I use the same tactic and it always seems to work for me. The only difference is that I set the Expires time to a big negative number like -1000.

Do you a notice a pattern concerning the pages that don't work?

try this on the page you want to expire:

Response.Cache.SetExpires(DateTime.Now.AddSeconds(1));
Response.Cache.SetCacheability(HttpCacheability.Private);
Response.Cache.SetRevalidationHttpCacheRevalidation.AllCaches);
