So finally the powers-that-be in our company figured out how to block certain websites via OpenDNS. Obviously we're already using OpenDNS as our DNS server.
I think that outside the system administrator and his company in our school, I was the first one to broach the topic of OpenDNS among the teachers, and how useful (my evaluation at that time) it would be to limit Internet access to legitimate sites. We've even tried using it in my brother-in-law's Internet cafe, and we are still using it in some units because Globe Broadband's DNS server is sometimes unreliable. However, my long use of the system alerted me to one big flaw of OpenDNS:
Now, I'm just wondering why Project Wonderful is blocked, when obviously useless sites such as Friendster, MySpace, and YouTube are not.

The default behavior of Firefox (and other browsers, I think), if the target of a POST could not be reached, is to keep that data in some place, so if you do a refresh, it will be reposted. However OpenDNS does not tell Firefox that the network is unreachable, instead it gives the browser a custom page not found message - a soft 404. The user is of course alerted to that fact, but for Firefox the transaction was okay, and so it discards the form input.In other words, you lose whatever you are typing if in case the server on the other side times out.
