Hi.

I've been using your library and I've noticed that when I do session.start() for the first time it will set a Set-Cookie in header, because it calls method regenerate. This is not desired when I just want to read and check if session exists. I could do this by first checking if a cookie named session is present, but I think it would be best to delegate this to resty-session, especially since we could change the name of the key and so on, so for now I removed the save instruct on regenerate (since I don't use it directly and I end up calling save after setting some data anyway). What do you think is the best way to proceed?

Thanks for the awesome library btw.
