[PATCH] HTTP proxy support for XMLRPC client

[mids]

Allowing HTTP clients to connect to a server through a HTTP proxy.
Especially for XMLRPC/SOAP usage.

For example something simular to:
http://markpasc.org/lj/200301/proxy.py

[mids]

from twisted.web.xmlrpc import Proxy
from twisted.internet import reactor

def printValue(value):
    print repr(value)
    reactor.stop()

def printError(error):
    print 'error', error
    reactor.stop()

if "__main__" == __name__:

    proxy = Proxy('http://betty.userland.com/RPC2',
http_proxyhost='myproxy.com', http_proxyport=8081)
    #proxy = Proxy('http://betty.userland.com/RPC2')
    proxy.callRemote('examples.getStateName', 41).addCallbacks(printValue,
printError)
    reactor.run()

As a probably better alternative to adding this to XML-RPC client, if #885 is implemented, and the client has proxy support (as it should), then XML-RPC clients will get proxy support for free.

Not sure if this is web or web2. Maybe Duncan will work on it, I likely won't.

isn't Issue #1895 a duplicate?

#1895 is about web2, this one's about web.

Looks like it's missing unit tests.

This should be done by adding a proxy-supporting Agent-alike and resolving #885.
