Support authentication by Cookie

[luminisward]

HTTP support only temporarily
HTTPS uses SafeTransport class

The changes you made breaks calls to my company wiki. When CookieTransport is used, the wiki returns a redirect (302) which generate this error:

ProtocolError: <ProtocolError for ********/lib/exe/xmlrpc.php: 302 Found>

The problem is visible in the apache logs:

# without CookieTransport.
xxxxxxx - - [14/Mar/2018:20:39:40 +0100] "POST /lib/exe/xmlrpc.php HTTP/1.1" 200 163 "-" "Python-xmlrpc/3.6"
# with CookieTransport.
xxxxxxx - - [14/Mar/2018:20:39:45 +0100] "POST /lib/exe/xmlrpc.php HTTP/1.1" 302 291 "-" "Python-xmlrpc/3.6"

It seems that the problem is from Dokuwiki server but I don't really understand the origin (misconfiguration of Dokuwiki, htaccess, ...). If you have any idea?

I'm not sure it will also break for other users so I prefer to add a parameter (cookieAuth) for making cookie authentication optional. I not really sure how to update your pull request before merging it, so I pushed a commit (b5e9d8b) for this behaviour in the luminisward-master branch.

Sorry I didn't take it into consideration, thank you for point out the problem. I set the parameter (cookieAuth) disabled, so it should work for old users.

I merge your pull request and release a new version (1.1.0) on PyPI.

Thanks for your contribution!
