why no cache!

[stevehof]

Pekka, or anybody care to explain the necessity of the following code in the head of the list.php page:

header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1

I'm assuming this is the reason why you get a 'page expired' when you try to 'go back' using the browers's back button.

THANKS!

Those headers are there only for password-protected exhibitions so that their URL's are not stored in proxies.
