cache does not expire

sdf1655a

I'm a bit puzzle by the php script failure to expire the cache. I even use the post method and use this script at the top of some of those web pages. Yet, it still did not work. I need a fix!!!!!

My script down below!!

<?php
// header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past -- to prevent caching
// header("Last-Modified: ".gmdate('D, d M Y H:i:s')." GMT");// always modified -- to prevent caching
// header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 -- to prevent caching
// header("Pragma: no-cache");

?>

Thanks,
Scott

Try removing the '//' comments from each line

Oh, I had that remark comment "//" removed before and after I post this script on the forum, I still get the same result. I was just adding comment and play around with it to see if it make any difference and there is none.

nope. i've got about 10 headers that supposedly clear cache on various browsers (not to mention apache sends some cache killer headers by default) but the only thing that i've found to work reliably is to advise the users to upgrade their browsers.

I noticed that your date seems to be bogus. There was no Mon, 26 July 1997; there was a Mon, 21 July 1997 and a Mon, 28 July 1997. I have no idea if a bogus date will behave the same way on the client side as a correct date, but I noticed it and thought I'd pass on the observation.

Hope this helps!

Just tried this and I am not sure if it makes a diference but I placed the code after the < head > declaration in html if you placed it before this it may not work?

Good luck

Andy
