Posted on February 11, 2009

Internet explorer seems to feel the need to cache everything, which can turn a simple ajax request into an IE nightmare.

Add this to the top of your php script, and all your IE Ajax caching problems will be solved!


header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
