I have no idea when this broke. So far as I know, the bug has always been there. I originally found it in a 2004 variant, and pretty much the same problem still exists. I'm seeing this with Perl 5.8.1 and 5.10.0 -- though that's probably not relevant, nor are the Linux distributions (Mandriva and OpenSUSE). In add_cookie_header, if the cookie version is nonzero and the cookie contents include a non-alpha (\W) character, it escapes any quotes or slashes in the cookie value. The problem arises when the server has delivered a cookie value that is ENCLOSED in quotes, i.e., Set-Cookie: member="whatever"; version=1; Path=/ When it comes time for add_cookie_header to do its thing, it generates Cookie: member="\"whatever\""; $Path="/" Cookie2: $Version="1" I don't know whether quoted cookie values are valid per the spec, but they do unfortunately occur (I can give you an example site, if you like). I guess there are 2 bugs here: 1) The biggest problem is with the quoting. I think I've fixed this by inserting one line in add_cookie_header in # do we need to quote the value if ($val =~ /\W/ && $version) { $val =~ s/^"(.*)"$/$1/; ### <<<<<<< A FIX $val =~ s/([\\\"])/\\$1/g; $val = qq("$val"); } 2) The second problem is with the treatment of the Path and version fields. They appear to be treated as if they are cookie values. And yet they are transmitted with a prefix of "$". I REALLY don't understand what's going on here, and I'm not inclined to mess with it.
