that is, given the two url of "www.a.com/sale/someFunction.js" and "www.a.com/sale/someFunction.js", and the javascript (someFunction.js) files have the same content. with squid, can I "cut" the part before "someFunction.js" when the url is given to generate cached object's key?
How do those two URLs differ? Did you mean to do something else in your example?
If you meant to change the path to the file in the second URL, which is what the rest of your question implies: there is no guarantee that someFunction.js actually has the same content at different URLs, so simply dropping the path part of the URL to get just the filename is not justified.
The only reliable way to do this would be to generate a MD5 or SHA1 hash of the file's content, and make the cache a mapping of pointers from URLs to unique content as well as having a cache of the content hashes. That's probably a fairly major change.
