Nadir,

I think in HTTPTransport::setProxy( const char *pcProxyHost, unsigned int uiProxyPort)

You need to force the unsecure channel to be used.

Klitos, is it true that all communication to the Proxy server is unencrypted, but the communication
from the proxy server to your web service is encrypted?

Klitos, 

I am willing to work on this if you help me understand what needs to be 
done.   There is an issue about tunneling here: 

http://issues.apache.org/jira/browse/AXISCPP-899

Maybe if you send me the traces and/or point me to something that tells me 
how this is suppose to work I can take a look into it.
