    # 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 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. And folks rely on
##   that...
