3 Ways To Make A Cross-domain Request In Javascript

I already know 2 ways (proxy using php and including an external javascript file). What is another way?

Solution 1:

You can use Access-Control-Allow-Origin: * in the headers coming from the server on the other domain.

That relies on the browser being modern, however. Won't work on IE older than 8.

See https://developer.mozilla.org/En/HTTP_access_control

Solution 2:

There is also Cross-Document Messaging combined with regular XHR.

An example of this can be seen on the easyXDM example page : http://consumer.easyxdm.net/current/example/xhr.html
