I have a css file being dynamically loaded. For example:
http://example.com/css.php?request=/skin/styles.css
On chrome is loads very fast and it has the 304 not modified header.
On FF and IE it has 200 OK status and loads in 6 seconds!
If I have a static css file for example:
http://example.com/styles.css
I get the 304 not modified on all browsers.
Any ideas what could be causing this? There is no browser specific rules in htaccess or httpd.conf
