Thanks for your reply, Phil. So, I basically modified twisted/web/xmlrpc.py so that
when it was calling connectTCP(), i substituted '::1' in place of self.host
and yes the method is called successfully.

I will consider your other hints and see if there is an easy way to work around this
in my particular use case.


Thanks,
Amit.
