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.
