From the client side you can NOT make a request into any other domains (not even the same domains different port like :81) then the host itself. This is the same origin policy .

However there are some workarounds to just proxy such requests, see Q: Make cross-domain ajax JSONP request with jQuery and Q: Ajax cross domain call
