Callback function for expired session for connect-redis in node.js

问题

I am using Connect on node.js with connect-redis as session store. Is there a way to attach a callback function to the the event when the session expires, so I can backup data from the session, before it gets deleted?

回答1:

Its impossible because the expiration is done at redis side. The connect-redis session store uses setex.

You can set a insane maxAge and do expiration by yourself using setInterval

OR

Fork the module :)
