[edit] Configuration Notes

This ruleset requires a very fast local DNS server. If you do not have a local and fast DNS server, you should not use these rules. The system will not serve up any webpages until the DNS lookup completes, and if you do not have a fast local DNS server this can result in the false impression that the web server is "slow". The server is actually not impacted by the rules, the server is simply waiting on the DNS server to respond to a query. So the web server, when using these rules, will only be as fast as the DNS server it is using.
