Hi Jerry, You can clear the cache by using the CLI command "clear url-cache". Again, please keep in mind that this does clear your entire cache, not just a single entry. On the other hand, cache entries by default expire in 7 days, though that can be configured to a value of your setting. For PAN-OS 3.1 devices, I believe this setting can be found on the Device-->Setup tab, under Dynamic URL Cache Timeout. If, after clearing the cache and/or waiting for the timeout to expire you are still experiencing problems, I would suggest that you upgrade to 3.1.9, as there were some bugs that addressed caching issues. Hope this helps, Doris
