Same origin host, different ports in JS

Question

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, because the 2nd host then gets the domain com.local:8080.

When I try to set the domain of the first one to com.local:8080 manually, the port is just snipped of and the domain remains com.local.

How can I enable DOM-Manipulation in this situation?

Answer 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.
