Call Web Service using proxy and http authentication

[wdveloper]

Hi everyone,

I am trying to call a webservice which requires an http
authentication.
To reach the ws, I must pass from a proxy http. So in the whole I need
go through two authentications before getting the ws working. I am
using SOAPpy and I'm getting quite crazy.
I am able to arrange this problem with simple http calls using urllib2
but for the ws i dont see any way out.

Does anyone knows how I can manage this stuff? Is there any better
solution or example code?

Thanks very much for your help,
