[issue1564508] RFC 2965 BaseCookie does not support "$Port"

[Martin Panter]

Martin Panter  added the comment:

The original report comes from . 
Anders was trying to parse a HTTP request Cookie field, something like:

BaseCookie('sessionid=a2be2e7debe71af8d88d350c4d14d768;$Path=/;$Domain=192.168.0.2;$Port="8000"')

The problem is that Cookie.py assumes names beginning with a dollar sign ($) 
are reserved attributes of a previous cookie-pair, rather than arbitrary cookie 
names. It is obvious that this was intended to support RFC 2965, although it is 
not documented. The module has a hard-coded list of reserved attribute names, 
and Port is not one of them.

IMO it would be better to treat (unknown) reserved attributes such as $Port as 
ordinary cookie names, and start a new “morsel”. Ignoring them would also be a 
better option than rejecting the whole cookie field. The dollar sign is valid 
for a cookie name (token) according to RFC 2109, RFC 6265, and the Netscape 
specification.

This won't go anywhere unless someone provides a patch.

Actually, I was just bit by this. In fact, RFC 2965 prohibits clients
from sending $Port if the port attribute was not included in the
Set-Cookie header.  But, it turns out that the mono System.Net library
(at least) will add the attribute any time the URI includes a
non-default port number. See http://go-mono.com/forums/#nabble-f1367  I
think this is technically their bug, but it might be nice to have
something like a non-strict mode in Cookie.py that would ignore
unexpected attributes for handling cases like this.

Grrr, the link in my last comment should have been

Yuck.
