I am working on an administration section to a site and I'd like it so that users can't press their browser's back button to navigate back. Some sites will display a "Warning: Page Has Expired: The Page You Requested..." error page. This is what I'm trying to achieve.
I've tried the following:
Response.Expires = 60 'also tried -60 here
Response.Expiresabsolute = Now() - 1
Response.CacheControl = "no-cache"
as documented on http://www.learnasp.com/learn/cachenomore.asp
but it has no effect.
What's the solution?
