Gautam, another question for you - in addition to the previous - if I have
a script that runs onload, which pulls some data from web servers, which
origin IP will that request have?  E.g., a regular request from a non-opera
client either has the ip of the client, or the client's ip is somewhere in
the X-Forwarded-For header. When the opera mini server executes javascript
that makes an AJAX request on behalf of a client, does it set XFF header to
the client ip? Or does it originate from its own IP?

Thanks!
