What's the best way to deal with cache and the browser back button?

Question

What\'s the best way to handle a user going back to a page that had cached items in an asp.net app? Is there a good way to capture the back button (event?) and handle the cache

Answer 1

RFC 2616 §13.13 says that History and Cache are different things. There should be absolutely no way for cache to affect Back button.

If any combination of HTTP headers affects Back button, it's a bug in the browser …with one exception.

In HTTPS browsers interpret Cache-control: must-revalidate as request to refresh pages when Back button is used (Mozilla calls it "silly bank mode"). This isn't supported in plain HTTP.
