HELP! Unwanted Server-Side Cache

Anon

Can somebody help?

I am using shared hosting, php 4.0.5, recently migrated from 4.0.3l or something.

All the pages to my site are dynamically generated. All files (index.phtml) are structured as follows: -

include('one.phtml');
include('two.phtml');
include('three.phtml');
etc.

And in each include file, there are DB connection processes, which generate contents depending on the request.

Problem : when I request index.phtml the first time, everything is correctly displayed. However when I request the same page a second time with different parameters, the contents of the first request is still displayed which is wrong and out-of-date, in particular contents in include files. Hence, the output of include files are being "cached".

I have done everything to ensure that this is not browser-based caching. Because exactly the same files used to run on the old servers and none of this happened.

Can somebody please tell me what is going on???

Zend has recommended doing the following to defeat server/browser caching:

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

Tried that already, still doesn't work.

Jason.
p.s.- I know that it's server-side cache.
(1) Added all the above header fields.
(2) The same scripts would work in the previous server(php4.0.3l) but not this one (Php 4.0.5).

Has anyone ever found out why this doesn't work? I am trying to re-validate a user after a cookie expires. The Authentication header keeps getting sent from the cache on the SERVER, so my script fires up and simply logs the dude back in.

I have the following headers:
header ("Cache-Control: no-cache, must-revalidate");
header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header ("Cache-Control: s-maxage=0, must-revalidate");
header("Expires: 0");
