Connect

Cookie parser

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
