How can I run code upon session death with Yesod?

I would like to run code whenever a Yesod session dies. For example whenever a session dies I would like to print "hello" to the console.

I did not use the scaffolding for my application.

Yesod's default sessions are done with clientsession. This works by storing encrypted data in the cookies from the browser—the server doesn't store any state. For this reason, I don't think there's a way to accomplish what you want.

You could switch to some sort of server-stored session, in which case you could kinda do this based off a session expiring, though you'd never be able to detect something like "the user cleared their cookies" which effectively kills a session.
