Having a list of blocked sites is pretty rudimentary. I was under the
impression that most services would block based on analysis of the content? I
must admit, I have no direct experience with HTTP content filters.

The telling sign was our customers calling and saying,
I hit the submit button, and I get "This Page Cannot Be Displayed"
in IE. What gives?
Then we looked in the server logs, and sure enough we never even
received the POST, and deduced it had been intercepted by a proxy. Some
helpful filtering vendors helped us confirm that the proxy settings
were such that the large POST was being turned back.
