How to configure Axis2 so commons-http client uses custom SSL socket factory like the contributed AuthSSLProtocolSocketFactory?

[Merritt, Norris]

Hi, I need to make Axis2 use a custom SSL socket factory so I can do SSL
client authentication. Commons-http supports the notion of custom SSL
socket factories, and there is a contributed one called
AuthSSLProtocolSocketFactory which looks like it does what I want. My
question is how to configure Axis2 to use this SSL socket factory
instead of the default one that it uses now.  I assume this can be done
without modifying Axis2 source code? Any pointers / help greatly
appreciated....
