random1 Posted April 16, 2012 Share Posted April 16, 2012 As per: http://www.queness.com/post/11156/speed-up-web-page-loading-by-deferring-javascript Does deferring JavaScript mean that it cannot be cached locally and needs to be fetched each time a page request is made? I've be not able to set the return as 402, Not Modified, like the rest of my CSS, JPG, PNG files.

Adam Posted April 16, 2012 Share Posted April 16, 2012 402? You mean 304? You can check using the "Network" and "Net" tabs of Chrome Developer Tools and Firebug, respectively. They report the status code returned for each request. There shouldn't be any reason why caching wouldn't work though; the script tags may be dynamically built but the browser will still make a normal HTTP request for them.
