TL;DR This plugin will remove query strings from enqueued static resources like CSS & JavaScript urls.
Resources with a question mark (?) or ampersand (&) in the URL often bypass a proxy cache server. Thus by cleansing the query string from the URL should significantly increase your WordPress site performance. The goal is to improve your speed scores in services like PageSpeed, YSlow, Pingdom, LoadImpact.
Additional funcitonality is to strip the protocal prefix to simplify asset loading to be relative to the protocal path. Attempts to force all linked assets to be of the same protocal.

Replace any plugin or theme asset source with your own desired source. Main purpose is to help WordPress users to change the slow third party scripts or styles which using by some plugins but slow load speed in certain countries.
Usually, you could use some coding skills to find the original enqueue method from the target plugin, then dequeue it, and enqueue your own version of asset file. But you need to take care and follow the same way how the original plugin enqueued and the dependency plus version. Otherwise, you might encounter some unexpected issues.
With the help of this plugin, you can easily replace the asset source file without coding skills.
This plugin is not meant to auto local host the third party asset file, but you could use for it too. Upload your own local version of asset file in a better and secured folder (maybe from your theme folder), get the public accessible url, use it on the plugin setting page. Just try it out and have fun.
<h4>How It Works</h4>
Once a new replacement set, this plugin will do a match on all queued asset styles and scripts source. If found the matching source, it will replaces target source URL with your replacement URL.

If the target asset url not using the standard WordPress enqueue script method by the developer, the replacement will not works.
