# Netscape cookies work the same as RFC 2965 with regard to port.
# Set-Cookie with negative max age.
# If turn RFC 2965 handling off, Set-Cookie2 cookies should not clobber
# Set-Cookie cookies.
# Cookie2 should be sent if *any* cookies are not V1 (ie. V0 OR V2 etc.).
# Cookies (V1 and V0) with no expiry date should be set to be discarded.
# RFC 2965 Quoting:
# Should accept unquoted cookie-attribute values? check errata draft.
# Which are required on the way in and out?
# Should always return quoted cookie-attribute values?
# Proper testing of when RFC 2965 clobbers Netscape (waiting for errata).
# Path-match on return (same for V0 and V1).
# RFC 2965 acceptance and returning rules
# Set-Cookie2 without version attribute is rejected.
# Netscape peculiarities list from Ronald Tschalar.
# The first two still need tests, the rest are covered.
## - Quoting: only quotes around the expires value are recognized as such
## (and yes, some folks quote the expires value); quotes around any other
## value are treated as part of the value.
## - White space: white space around names and values is ignored
## - Default path: if no path parameter is given, the path defaults to the
## path in the request-uri up to, but not including, the last '/'. 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 everytime I think of that code).
## - Expires: You'll get all sorts of date formats in the expires,
## including emtpy 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. And folks rely on
## that...
