After the Timeout for the WebClient expires or the user simply calls a Page directly buy changing the link all of the filters may be gone. This is normally not that critical but there are some Pages where some records are filtered out using the filtergroups and user can normally see only filtered records. After the timeout has run out or the user has called the page directly all of the filters are gone and user can access sensitive data. We have implemented relatively simple solution for that after those pages have been identified but it would be good to have a system wide solution for that. Maybe a pull request on a System App repository?
