Pronto : A jQuery plugin for faster page loads

Building on concepts like pjax and TurboLinks, Pronto is a simple way to harness the speed increases that HTML5’s pushState() can provide on nearly any site imaginable.Using a “partial page load” technique, Pronto reduces the over all server load and font-end render time by only updating pieces of a page instead of the entire document. On many sites, basic layout like the header and footer remain generally the same page to page. The overall browsing experience gets a little shot of caffine by only requesting these pieces of markup once, as well as assets like stylesheets, scripts or fonts.
