How to fix IE Caching AJAX pages.

[Will]

Just thought I'll share this with you because it took me ages to realize why it happened.

I was using AJAX to do some form stuff when the use clicked a button, but it only worked the first time I spent ages thinking it was me but then I found an article on the Internet saying the IE caches the pages.

To fix this just put this at the end of the URL you are calling in the javascript:

 

+ "&ms=" + new Date().getTime();

I'm sure you can guess that this makes the URL different every time so IE can't cache it.

The following block of headers, placed in any dynamic page before a response has been sent to the user, will give you the same effect without messing with your query strings (the first two help with SEO as well).

 

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
