Axis2 - can I obtain the HTTP client?

I use a Axis client on a non Axis server.
I need to overide(on clietnside) the Content-Encoding received in the 
HTTP header from the server because the server sends an invalid 
Content-Encoding.
Can I  obtain the HTTP client from the stub class? I want to try to 
rewrite the header before it gets processed as described here:

Thank you.
