I had a firewall rule that blocked access to a website for requests where the country was not in a list of 3 countries (e.g. a, b, c).
I later changed the firewall rule by removing one of the countries (e.g. the list is now a, b).
I’ve tested various computers in country c. Some get access denied, but others are not blocked. Is there some kind of cache that remembers a particular computer and continues to allow access until the cache is cleared? I tried deleting browser cookies on the computer in country c, but it’s still not blocked.
Thanks for your help
