thanks!!

You'll need httplib which luckily come with the stdlib so no
need to install 
anything.

Something like this should get you going:

conn = httplib.HTTPConnection(remote_server)
values = '&'.join([ '%s=%s' % a for a in values.items()
])
headers={'Content-Type':'application/x-www-form-urlencoded'}

conn.request(method, url, values, headers=headers)
res = conn.getresponse()
data = res.read()
return (res.status, res.reason, output)

the important bits here are our crappy makeshift 
application/x-www-form-urlencoded rncoder which
is the values line and our setting of the content-type. We
also 
need to make sure the method passed to conn.request is
'POST' or 
'PUT' (almost certainly POST) as these are the only ones
that accept 
a body. I think the cgi module may have a better way of
doing the 
encoding, but i've never found it.

this as it will
properly quote and convert special characters.
