Script and stylesheet combining

By default, each of the RadControls for ASP.NET AJAX serves a set of files (JS code and stylesheets) required for its proper client-side operation. When loading a page with several controls on it, the number of these files can become very large, often resulting in a reduced page load time and increased traffic. The reason for this is that browsers make a separate request to the server for each of these resources.

Sitefinity CMS uses the RadScriptManager and the RadStyleSheetManager to combine all resources into a single requests. It uses the RadScriptManager to combine all JavaScript resources into a single request and the RadStyleSheetManager to combine all stylesheets into another single request.

IMPORTANT: In case you are working with MVC-only pages and widgets, to combine scripts and styles for the MVC views, follow the procedure in Administration: Enable ASP.NET bundling and minification.
