I am using ClientCookie for login on to servers and browsing them as
authenticated users.
I kept getting "HTTP Error 400: Bad Request" errors when submitting my
forms. So I boiled it down to a simple example.
When I try to use ClientCookie.urlopen() on my private network with ip
numbers like "http://localhost:8081/test_site/logged_in", it works fine.
If I try to call the same site through the Internet, with a url like:
http://www.mxm.dk/test_site/logged_in I get the 400 message. But only
when using "post". 'get' works fine :-s
On the Internet I go out through a gateway, so my external IP is
different than my internal.
I assume that it causes an url mismatch somewhere. With my local ip
being set in some header by urlopener, and the server expecting the
remote ip.
But I have no idea as to how I can avoid it? Any takers?
