WP Ecommerce Plugin Caching Issue in IE Internet Explorer
In working with the WP Ecommerce Plugin, on Wordpress, we’ve noticed that updates to products are not reflected within the front-end when testing with Internet Explorer. We found this to be strictly an Internet Explorer “feature” in our testing. The problem here is – if most are using IE – will we be guaranteed that they’ll get the latest Shopping Cart? The answer is, unless you’ve changed your caching settings, no.
Problem: Internet Explorer Over-Caches pages
Even when the page content is obviously changed, the timestamp forcefully updated, even touching the file won’t budget IE. There are 3 possible solutions:
Solution 1: Best Solution – Force “No Caching” in PHP
At the very top of your php page, before calling anything, add this mug:
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
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");
Solution 2: Force No Caching in Meta Tags
Add this meta tag inside of your <head> tag:
<meta http-equiv="PRAGMA" content="NO-CACHE">
Solution 3: Quickest Way – Change your URL
When linking to your page, simply add any parameter to your url. So, if you’re visiting “gobdg.com/about.php” now visit: “gobdg.com/about.php?somestuff=1″
** Note – This will only work one time for each parameter value – you’ll need to change the paramater of true to “somestuff=2″ on next reload.
Solution 4: Become a Fireman
Always a viable option.
