Hi.
The standard Cookie module does not parse date string.

Here is and example:

>>> import Cookie
>>> s = 'Set-Cookie: key=value; path=/; expires=Fri,
21-May-2004 10:40:51 GMT'
>>> c = Cookie.BaseCookie(s)
>>> print c
Set-Cookie: key=value; expires=Fri,; Path=/;

In the attached file I have reported the correct (I
think) regex pattern.

Thanks and Regards Manlio Perillo

This bug is in error; RFC2109 specifies the BNF grammar as:

av-pairs = av-pair *(";" av-pair)
av-pair = attr ["=" value] ;
optional value
attr = token
value = word
word = token | quoted-string

If you surround the date in double quotes, as per the RFC,
then the above works correctly.

Closing as 'not a bug'. This decision could be reversed if there's some
common application or software that returns cookies without quoting the
date properly.

insomnike wrote that RFC2109 requires double quotes.
This is right, but many servers follow the Netscape spec.

Moreover (as I can see) the same Cookie module follow the
Netscape date spec!

>>> import Cookie
>>> c = Cookie.SimpleCookie()
>>> c['key'] = 'value'
>>> c['key']['expires'] = 10
>>> c.output()
'Set-Cookie: key=value; expires=Sun, 06-Jun-2004 10:36:24 GMT;'
>>> s = c.output()
>>> nc = Cookie.SimpleCookie(s)
>>> nc.output()
'Set-Cookie: key=value; expires=Sun,;'
