How do I make my sessions last cross-subdomain in Node.js Express?

Question

And all other subdomains.

I want sessions and cookies to hold!

Has nothing to do with Express. It's the settings on the cookie itself that matter. Set its domain to .mydomain.com and you should be fine.

EDIT: The OP wanted more details, so here are the examples from the code.

  connect.createServer(
      connect.cookieParser()
    , connect.session({ cookie: { domain : ".mydomain.com" }})
  );

and

 res.cookie('remember', 1, { domain : ".mydomain.com" });

should work.

How do I do that? I simply use Express to handle my cookies... I do req.session.abc='123'; console.log(req.session.abc); – user847495 Aug 16 '11 at 07:03
Do I need the last part (res.cookie) if I already did it in createServer? – user847495 Aug 16 '11 at 08:29
The arguments in createSession control the cookie(s) created to support the session. If you create any cookies by hand, you have to set the domain by hand. I believe. Try it and see. – Michael Lorton Aug 16 '11 at 16:01
For **localhost** you **have to have two dots**, ``domain: 'localhost'`` does not work. This does work: ``domain: '.app.localhost'`` for all the subdomains of app.localhost, such as: ``api.app.localhost:3000/'`` – AmpT Feb 27 '14 at 13:31
