Cache Prevention for Dojo xhr requests

 * Cache Prevention for Dojo xhr requests
 * Adds no-cache header and enables dojo's preventCache feature
 * for every dojo xhr call. This prevents the caching of partial
 * refreshs.

        if( !dojo._xhr )
        dojo._xhr = dojo.xhr;
        dojo.xhr = function(){        
                var args = arguments[1];   
                args["preventCache"] = true;
                args["headers"] = { "cache-control": "no-cache" };
                arguments[1] = args;
        	dojo._xhr( arguments[0], arguments[1], arguments[2] );

This small snippet prevents caching of all Dojo's xhr request (which includes Partial Refreshs)
Just add it the code to a <xp:scriptBlock> on your XPage.
