[mod_python] Can i have both Marshal and Signed Cookies withPublisher?

That would be understandable. The Cookie.get_cookies() expects you
to supply a class type and since there are multiple cookies stored of
differing types then the class type supplied may not be able to unpack
all of them.

There probably needs to be a Cookie.get_cookie() so you can say that
you only want to get a specific cookie by name. Not sure I understand
why there isn't one already unless I am missing something.

Besides writing your own version of Cookie.get_cookie(), the only other
way of getting around the problem for now is to set the 'path' attribute
of the cookies so that the cookies only get delivered to their respective
applications. But then, even that isn't necessarily going to help in all
cases because sessions use cookies as well, so it you want to use a
marshalled cookie in the same context as a session is used you are
similarly going to have a problem if the session is signed.
