I am experiencing a strange behaviour of my application in Chrome browser (No problem with other browsers). When I refresh a page, the cookie is being sent properly, but intermittently the browser doesn't seem to pass the cookie on some refreshes.

This is what I am using for page headers:

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Thu, 25 Nov 1982 08:24:00 GMT"); // Date in the past

Do you see any issue here that might affect the cookie handling? Thank you for any suggestion.
