Do you mean the session ID itself?  I thought that was just randomly
generated with Vend::Util::random_string(), using the $random_chars
value ([A-Za-z0-9] minus [O01l]).  That would be captured by the
existing default (\w{8,32}) pattern.  The current CookiePattern
directive allows other patterns to be matched, but that doesn't affect
the Session ID generation.  The only reason to use CookiePattern at
the moment, as far as I can see, is because it's required when using
the CookieName directive.

The default (hard-coded) cookie pattern allows for ':' (separating
the ID from the IP/user/host) and chars like '-' and '@' in the middle
of a user/hostname.  My patch proposal shouldn't have removed any
of that, so I would expect existing setups to work without change.

Correct me if I'm wrong.  I have been known to be. :-)

The current (\w{8,32}) could be changed to ([-\w:.]+?), which would
allow for a more liberal session ID match and still fit in with the
patch proposal.  I can't see that as being necessary at the moment,
unless people are creating their own session ID naming schemes for
some reason.
