Same Origin Host, Different Ports In Js

for the two hosts http://1.com.local/ http://2.com.local:8080/ how can I use document.domain to enable DOM-Manipulation between the two? If i set both to com.local it doesn't work

Solution 1:

You cannot. Sorry - same origin is including the ports

You can use CORS and ajax to copy some stuff from one server to the other if you enable this.
