Node.js & Express session problem

Question

I\'m having a problem with sessions, where sometimes the session variable I just set is undefined on the next page request. I typically have to go through the flow

Answer 1

I filed an issue against Express about github, but figured out what was wrong a few minutes later. Not sure if you're having the same problem, but for completeness:

In my case, I was testing by going to http://localhost:8003 but the OAuth provider was redirecting to http://hostname:8003. Same box/server/webpage, but different domain names means the browser sends different cookies and consequently, express gets different session ids and session data. As soon as I started testing at http://hostname:8003, everything worked just fine.
