[sitethumb://js-optimizer.sourceforge.net] JavaScript Optimizer - JSO is a project that allow you to manage easily your JavaScript and CSS resources and to reduce the amount of data transfered between the server and the client.
To perform this, the following optimizations are performed :"Cache optimization : by adding a timestamp and headers informations, the caching resources is more efficient". "JavaScript files merging, minimizing, and refractoring, if possible". "CSS files merging and minimizing if possible." Through these 3 steps, the data transfered is significally reduced. The resources managing is externalized in an XML descriptor, which make it really easier to maintain.
