There are some detailed explanations of how this works, as it was previously described when the feature was first implemented as a Firefox plugin. To answer an earlier question in the thread, Safari does *not* report to Google for every URL you hit - the system involves a locally cached database of hashes for restricted URLs (at the domain level, I believe, not IP or page level). As far as I recall, the hashes are in fact broken in two parts (perhaps just split in half?)... if the URL you navigate to matches the first half of a hash, then it is a possible match, and then (I believe) Google is queried to compare the rest of the hash - so the vast majority of the time Google has no idea whether you've hit a given URL, only when there's a possible match, which should be quite rare - I know I've yet to see this feature activate. I'm sure my recollection is at best only partially accurate, but I do know this mechanism does not hit Google for every page, domain, or IP you surf... most of the checking is done against a local database, which is periodically updated. Search Google for more information - I know there were several blogs which posted detailed descriptions of this feature when it was launched, since Apple provided little information about it. -R _______________________________________________ OSX-Nutters mailing list | [email protected] http://lists.tit-wank.com/mailman/listinfo/osx-nutters List hosted at http://cat5.org/
