forcing refresh?

ksw

I'm trying to figure out how to prevent a PHP page from caching in the browser, in memory, or in some server cache somewhere.

My basic problem is like this: my general coding style is to create a ton of subFunctions that render html, authenticate users and whatnot, and call them with one main superFunction to build the page. However, when I tweak a subFunction, like to add an echo or whatever, I find that the results of my tweaking don't show up immediately when I view the page because as far as the browser is concerned, the page hasn't changed.

I have this code at the top of each page I make:

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

but it doesn't seem to be helping things ...

To deactivate any proxy-cache, code this four header instructions at the very beginning of every script:

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // some gone date 
header ("Last-Modified: " . gmdate ("D, d M Y H:i:s") . " GMT");
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 
header ("Pragma: no-cache"); // HTTP/1.0

To deactivate browser cache insert following meta tag to your produced html codes

 
<META http-equiv="expires" content="0">

I have done all that and it still does not work, I get the same non refreshing problem and have to empty my cache dir manually everytime before I can see the new posts on the portal forum of our board.

I have no idea what to do.. I have heard about the incompatibility issues between PHP and Apache 2x and that might be causing the problem, in that case none of the above would fix the problem I believe.. I hope I'm wrong but for the moment I can not do anything about it since I am being hosted and I can not ask the host to downgrade to Apache 1x !

So any more help on the issue would greatly be appreciated.

I had the same issues when I ran 2.x with php... I don't know what to say... I downgraded (it doesn't even really make a difference for me) and it works fine now.
