Do you know how can I store the session using MongoDb (I'm using mongoose).

@limoragni, you can use session-mongoose, works fine but as explained, not ready for production ... https://github.com/donpark/session-mongoose

res.signedCookie(name, req.session, { signed: true });

in both source code & official docs, there is NO res.signedCookie, but only res.cookie(name, req.session, {signed: true}); which works exactly as setting singed cookies!

Is it possible to use couchDB for session storage?
