Javascript file loading

[Pawanpreet Singh]

Hi All
We know that if we have included a js file in an html/jsp file, an on opening same url in different browser window, everytime js file is loaded along with page. But i want it to store in browser cache and i want that only one time, js should be loaded, and if same url is requested, its js should not be loaded with page and page use same old ones from browser cache.

The external javascript files are designed to be cached by the browser. If they are not being cached, then it is most likely the browser settings are looking for a new version on every visit.

Hmm, I know that if the browser is set to cache everything and only check for new content with a new browser instance, it is possible to set headers to make sure a page or a file is never cached (of course the browser has to recognize the headers, but it works with IE and Firefox). But is it possible to do the opposite - to force the browser to cache a resource even if the settings are "check for new content every visit to the page."

For example, if I have the same image displayed hundreds of times on a page, I don't care what the browser settings are - I don't want hundreds of requests for that image coming to my server from the same client.
