Yes. Absolutely. \n\nMany folks clear their cache or even turn it off completely (like me).\n\nEven if the unneeded JavaScript is cached it is still run by the browser.\n\nCheck out http://tools.pingdom.com/fpt/.\n\nThis tool tests the load time of that page so you can analyze it and find bottlenecks in load time.\n\nWhen you say different headers what CMS are you talking about?
