In case anyone stumbles in here with the same issue, I was able to solve this pretty easily...
As long as your library includes aren't port specific, and your $.post () url is pointing to the port you need (http(s)) then, there won't be any problems. Your library call should be something like this: <script type="text/ javascript" src="/scripts/js/jquery-1.3.2.js"></script> hope it helps someone...
