Hi all,

It seems like a few people are interested in persistent connections...
below is how I got suds working with httplib2. I don't have a need for
cookies or proxies etc so the solution below is lacking them (if
anyone needs them take a look in suds/transport/http.py and the
httplib2 docs - it doesn't look like it would be too difficult to
add). Its also lacking any exception handling (although you'd probably
just catch them in your application). Reusing connections gives a nice
performance boost for my use-case. Anyway, thought I'd share it since
there seems to be some demand :-)

        response = Httplib2Response()
        response.headers, response.message = self.http.request(url,
"PUT", body=message, headers=headers)
        return response

wsdl = "file:///yourWsdl.wsdl"
http = Httplib2Transport()
client = Client(wsdl, transport=http)
