Ok thanx,
I'm fairly new to Python and I don't know anything about browser
identification. Do I add it with .putheader() ?
my code looks something like that:
------
        h = httplib.HTTP('www.domain.com')
        h.putrequest('GET', url)
        h.putheader('Cookie', 'username=myname%123456789')
        h.endheaders()
        errcode, errmsg, headers = h.getreply()
        f = h.getfile()
        print( f.read() )
------
I get a page where it says something about that my login was
successful (so I think the cookie part works) but it also says "We
don't support scripts" in the html code.
How can I fake the browser identification? I couldn't find useful
information about it on the net.
