After sending this I realized I sent it too early. The code below only
works after you get both documents under the same domain because of
cross-site scripting protection in the browser. To bring them both under
the same domain you can either setup Apache or Nginx as reverse-proxy or
write a servlet deployed with your GWT server side code that proxies
requests to the other domain. If you just have a couple of pages to proxy I
would do the servlet approach. I've done both methods. There are a couple
of example proxy servlets you could start with and deploy one of them in
your web.xml.
