I assigned a kid's device to group "kiosk", and to that group I assigned the blacklisted RegEx
. (period, i.e. deny everything) and the whitelisted RegEx
(\.|^)zdf\.de/kinder$ (from a German TV channel).
My plan is to allow only access to (www.)zdf.de/kinder and paths below this (e.g. zdf.de/kinder/logo) but to not allow access to (www.)zdf.de and to (www.)zdf.de/<anything else than 'kinder/*'>.
However, this does not work, and even after studying the rich available information about RegEx and examples, I have not managed this, i.e. as long as I do not also add the whitelisted RegEx
(\.|^)zdf\.de$, the to be allowed path cannot be accessed; thus, everything (also above) can be accessed, which I do not want.
Hopefully, I have described my problem precisely enough and well to understand. Thanks for sharing your thoughts with me how/where to further adjust my RegEx!
