How to receive web page faster with resouce caching

view full story

http://serverfault.com – When sending request on HTTP server which is flooded by other requests my request will be in the queue and after some time server will send response. Now my question comes : Would it help to make on-fly html page modification in order to do not download static resources (e.g. pictures,javascripts,css) from the server but from my local storage so response time will be faster because my browser will not have to ask for these resources or modern browsers use some kind of caching all the time ?
