Connect

Cookie parser:

Status: Deprecated. This middleware will be removed in
Connect 3.0 and will be replaced by a cookies middleware,
which will use cookies
and keygrip.

Parse Cookie header and populate req.cookies
with an object keyed by the cookie names. Optionally
you may enabled signed cookie support by passing
a secret string, which assigns req.secret so
it may be used by other middleware.

Examples:

connect()
  .use(connect.cookieParser('optional secret string'))
  .use(function(req, res, next){
    res.end(JSON.stringify(req.cookies));
  })

String secret
returns Function
