URL Filter update - users not seeing changes?

cenders — Fri, 19 Aug 2011 20:43:24 GMT

1. If a URL is incorrectly categorized, I submit a change to Brightcloud.

2. Brightcloud emails me the next day (or two) and says the change was accepted and is in the latest DB.

3. I confirm on Brightcloud's website that the URL is newly categorized and what version of the DB it is in.

4. I confirm that my PAN devices have that version of the URL DB (or later). If not, I perform a manual update (via CLI).

But when I try to browse the site, I'm still seeing the old classification for that site (which is blocked by policy).

Is there a delay from when the update occurs before the system sees the new category? Can I cycle a service on the box to make this quicker?

You must clear the URL-cache on the command line: clear url-cache

Just to elaborate a little more, URLs are cached on your device, so even if you see a category update via the BrightCloud website, you must wait for the device cache to expire before it can pick up the new categorization. Clearing your entire cache will certainly force a cloud lookup since the URL in question would no longer be cached on your device, but do keep in mind that you would be clearing your entire cache.

How long does it take for a device cache to time out?

By default, the cache has a timeout value of 24 hrs. We recently identified a bug recently where this variable was not getting configured properly, but this should be addressed in a future release (meaning you'll be able to configure this to a number of your choosing).

We are facing a problem with a lot of "unknown" URL's (Brightcloud DB) although the URLs in question are well known sites. We already filed a case but the problem could not get fixed until now. We are on 5.0.7.

After clearing the url-cache all works fine again for a unknown amount of time (days,weeks). But clearing the url-cache manually every now and then cannot be the solution.

Now I am reading about a bug in the cache timeout value.
