John,

Here's how we "handle" the situation.  We have an internal Netscape Proxy server and 
entered a subscription with Secure Computing's (www.securecomputing.com) SmartFilter 
product.  The product runs on Netscape and Microsoft Proxy, NT and Unix.  The software 
was cheap and the subscription is cheaper.  All clients point their browsers to the 
proxy server and the firewall is instructed to allow only http access from the proxy 
server.

SmartFilter categorizes a site based on web page content (Sex, Hate, Criminal, Job 
Search, Chat, etc.).  I can block an entire category.  Should one of my users 
"accidentally" (of course) hit a blocked site, I've customized the error message (a 
simple process as well) to report why the site was blocked and who to call should the 
site not be blocked.

Oh yes, unblocking a site is fairly simple as well.  "Fairly" only because to modify 
the blocking rules, while only editting a text file, requires stopping/starting the 
proxy services to become effective.  Not only can a site be unblocked, but it can be 
blocked as well ... Open up the sports category, but block the home site of your rival 
NFL team *grin*.  Blocking/Unblocking can be performed at a URL level all the way down 
to a specific page.

Secure Computing updates their categorization list once a week.  Unfortunately with 
NT, there is no supplied way to Cron the ftp download, unless I go get some other 
software and write the scripts.  For me, the 5 minutes to download and put into place 
the new category files once a week is no biggie.

Secure Computing blocks by dotted decimal notation as well as URL.  

Sorry to be wordy, if you have any other questions, feel free to email or call.

Doug
