As @Athasach said, according to the jQuery docs, $.ajaxSetup({cache:false}) will not work for other than GET and HEAD requests.

Of course, this would not work for service urls that you do not belong to your project. In that case, you might consider proxying the third party service from server code rather than calling it from client code.
