Right now I'm not sure if this is a bug anymore, and it's probably the 
reason I got no answers for this, details below.

When I did this statement:

p = Proxy('http://localhost:7080')
p.callRemote(egg, spam)

Twisted then sends the request:
User-Agent: Twisted/XMLRPClib
Host: localhost
Content-type: text/xml
Content-length: 189

<?xml version="1.0"?>
# Blah Blah

"POST  HTTP/1.0" becomes an invalid request because there's no path 
anyway. Still, the twisted xmlrpc server carries forward the request to 
twisted.web.xmlrpc.XMLRPC.render() anyway, but this time, the 
request.content (line 103 in xmlrpc.py) is an empty StringIO, and when 
passed to xmlrpc.loads(), returns the exception.

If the request is wrong, shouldn't twisted.web complain about it at a 
point earlier than the XMLRPC resource? If it lets the request thru, why 
does request.content becomes empty. Or, shouldn't the XMLRPC client adds 
a '/' at least when there is no URI (URL?) in the request?

That's all for now.
