Pronto is a free jQuery plugin that will load a webpage faster than ever. It’s not only a great way to gear up the speed of a webpage but also a nice idea to improve user experience. Actually, Pronto use a partial page load technique, which reduces the server load and the font-end render time by updating the pieces of a visible page rather than loading the whole document.
