All, We migrated to Mendix 7.23.15 recently. And post upgrade, we notice that sometimes when a user session is timedout, it shows login screen, which is quite normal. But the URL has a strange query parameter. http://localhost:8080/p/administration?messageCode=419 This query parameter is carry forwarded (or kept intact) if the user logs in and starts using the application. This starts happening only after the upgrade. Any one facing same issue and any pointers to avoid this?
