Note ## that this is entirely different from what the spec says. ## - Commas and other delimiters: Netscape just parses until the next ';'. ## This means it will allow commas etc inside values (and yes, both ## commas and equals are commonly appear in the cookie value). This also ## means that if you fold multiple Set-Cookie header fields into one, ## comma-separated list, it'll be a headache to parse (at least my head ## starts hurting every time I think of that code). ## - Expires: You'll get all sorts of date formats in the expires, ## including empty expires attributes ("expires="). Be as flexible as you ## can, and certainly don't expect the weekday to be there; if you can't ## parse it, just ignore it and pretend it's a session cookie. ## - Domain-matching: Netscape uses the 2-dot rule for _all_ domains, not ## just the 7 special TLD's listed in their spec.
