[OpenLayers-Users] wmsgetfeatureinfo with url on alternative port not firing on client side

[Andreas Hocevar]

Sounds like your app script is hosted at http://160.97.12.223:80/. To
send AJAX requests to http://160.97.12.223:8000/, you would need a
proxy. This is because of the browser's Same Origin Policy (different
port - different origin).
