I wonder what exactly the version nameing does?

like jquery.js?ver=1.4.4

I mean if I use a cdn like this jquery/1.4.4/jquery.min.js?ver=1.4.4 but another side has jquery/1.4.4/jquery.min.js?ver=1.3.2 in there, does this effect caching?

Reset to default 8

Yes, by changing the =1.4.4 to something else, it forces the file to not be cached by the browser when a user es back to the page. So if you upgraded to a new version of JQuery say 1.4.5, and you wanted to make sure that the client got the most current version of the file, you change the end of the url. This makes the browser think that it's a brand new file and forces it to download the new version.

(Having the version at the end helps you easily identify which version of the file you have, but that is totally aside from what is being asked :) ).
