Fix allow_redirects

[espenhogbakk]

Hi,

I have problems with the "allow_redirects" to the Request object. It seems that if you specify "allow_redirects=False" it still follows redirects. I think I've found the source of the problem on line 169 in models.py:

while (
            ('location' in r.headers) and
            ((self.method in ('GET', 'HEAD')) or
            (r.status_code is 303) or
            (self.allow_redirects))
        ):

Shouldt the or (self.allow_redirects) be and (self.allow_redirects)?

When allow_redirects is set to True, the redirection of non-GET/HEAD requests is allowed. RFC 2616 10.3 says that these redirects should only occur w/ permission of the user (therefore, the flag).

When allow_redirects is set to False (default), GET and HEAD requests are redirected as usual, and a 301 result of a POST, will not be redirected.

I'm considering renaming allow_redirects to avoid confusion.
