Are there any security issues with getting a cookie with jquery and sending it via nowjs function as opposed to getting it via the request on the server?
var session = $.cookie('session_cookie');
now.distributeMessage(session);
vs
req.headers.cookie
I don't see the reason to send cookies from the browser side, since they are transmitted either way each time you make a request to the server. No need to duplicate this feature, just use:
req.headers.cookie
