llHTTPRequest user agent and port

I have a web-page that wish to contact through a SL scripted object but the web-page will not pass the info I wanted to recieve to my script because it does not recognize the user agent information sent by llHTTPRequest. I tested this using python and the urllib2 libraries.

Is there anyway to change this part of the headers? Also does llHTTPRequest allow "address:port number" as a url? If not, is there a good work around for this? I searched but couldn't seem to find the answer to either of these questions.

Thanks in advance.

You can't change the user agent or other headers.
http://address:port/ works fine.
