Starting with Zen Cart® 1.5.2, additional rules have been added to your store's /includes/.htaccess instructing the customer's browser to cache images, PDFs, CSS and javascript files for certain periods. While that caching provides your site with a performance "boost", it's not without cost … what happens if you've added a plugin that adds some styling to your current template's stylesheet.css? The short answer is that until the customer specifically refreshes their browser or clears their browser's cache (possibly multiple times), those changes won't be pulled from your site because the browser has been told to cache that file's contents!
/includes/.htaccess
stylesheet.css
That's where File Auto-Versioning comes into play. This plugin adds a version string to those file "assets" so that your customers' browsers are always pulling in the most recent content and busting the cache held by the browser!
