mod_http_bind + ejabbered 2.1.5 + CentOS 5.5 x86_64

Is it possible to send out customized headers with the response of the http-bind?

I need to set the Access-Control-Allow-Origin header.

My website uses a JavaScript Jabber client along with http-bind to make the connections.

The web server is domain.com and the ejabberd server is xxx.domain.com, in which I am getting an error from all browsers saying the following...

XMLHttpRequest cannot load http://xxx.domain.com/http-bind/. Origin http://domain.com is not allowed by Access-Control-Allow-Origin.

Any ideas to get around this or how to set the header to allow my origin?

This is urgent and I am grateful for any input!

Yes, it's possible to tweak ejabberd source code to provide additional headers.

mod_http_bind returns that header since ejabberd 2.1.3, related to the ticket https://support.process-one.net/browse/EJAB-1168 See this example request and response using ejabberd 2.1.5:
