I have a handful of users who are allowed to bypass blocked pages and I review the logs of bypassed domains to determine which ones should be allowed permanently for all users. Sometimes they will bypass a blocked domain on behalf of a student for homework reasons, but we don't want that domain to be accessible for a long period of time thereafter.
So when a user does bypass a blocked domain, how long is that bypass valid? Is it based on a certain period of time or just for that session or something else? At what point will returning to that same domain trigger a block and prompt for bypass authorization again?
