问题
On asp.net, we have a session expire event. I'm using node.js with express.js and the default memory store for sessions. Every time I restart node, the sessions are lost. Ideally, I'd like to save the sessions to the db (can't use redis).
Is there a session expire event?
回答1:
If you want to save the sessions to a database which isn't Redis, there are more solutions: https://github.com/senchalabs/connect/wiki (check the Session Stores section).
As far as I know there isn't such an event for cookie/session expiration (I've looked at the code for Connect and didn't find such a feature).
Also if you don't want to use sessions with a database at all, the are several modules for that (storing sessions in cookies, encrypted):
