And also, I am not convinced the the practice "take out some part of jQuery and minify it" is wort of the effort and is good practice, since that way, you probably avoid all caching mechanisms on the way from you server to the users browser. Of course the question is if the browsers are smart enough to keep cached single copy of jQuery once they download it ....the question is simple answered: caching is based on domain *and* URI including all params, always, anywhere for proxies as well as for browsers and no browser is in the position trying to be smart in that context because any other behavior would be broken a web client is not allowed to say "hey, i have a /jquery.js in the cache from application A and re-use it for application B" because that would be *easy* attack vectorIf web client had a chance to say "hey, i have a /jquery.js in the cache from application A with checksum 'bla', I can reuse it for application B, since it request /jquery.js with the same checksum". Actually just checking checksums could be enough. But nobody implemented it yet I guess.
it don't work that way and it won't ever work that way because you would need to implement that feature in any server, any client and any proxy software out there after get it into the HTTP RFC which is unlikely to ever happen
so the whole question is far oustide the scope of the topic
