[keycloak-dev] advice on back button

The current thinking for browser back button is to set: Cache-Control: no-store, must-revalidate, max-age=0 There are possible security issues with this that I don't know if we should do this or not. Don't know if you remember how ClientSessionCode works, it uses a hash of the client session id and the action key currently stored in the. When you switch from authentication to required actions, the action key changes. Now, if you hit the back button on a required action page, it would take you back to an authentication screen. The code check would fail because the action keys don't match. Do we actually need this action key stuff? Can we just let the flow manager put the browser in the correct state? So if an "authenticate" url is hit and the flow is on required actions, just redirect to the required actions URL. I just worry that this is some sort of security hole somehow. Maybe we're better off just reseting and restarting the flow entirely. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
