How to avoid "Page has Expired "?

[Anon]

Guys,
It's so annoying to get "Page has Expired - please reload" error every time I try to go back from one *.php page to another.
Could anyone suggest if it's possible to tune apache/php settings?

if it is in IE 5.5/6 you need to add a header to you pages saying cache the pages. You can also do it with session_register, or mess with pragma cache.

Basically you need to tell the browser to hold the cache for you.

something like:
header("Cache-control:public");

at the top of each script.

Try a Google search or the manual for more info. I don't have the exact code at hand.
