We have dramatically improved the cache-ability of resources served from Storesonline Pro.

Web caching is the temporary storage of images and other resources used on an HTML page. When the browser can fetch the resource out of its cache (local hard disk) the web site appears to load almost instantaneously! This will only work on your live site because secure (https) resources will not be cached and while previewing, your site is in secure mode.

Thanks to Brian D. Davison's site Web-Caching.com, we were able to work out some of the difficulties with Internet Explorer using his cache analysis tool.
