Apache, the server and not the Indian tribe, is a fickle mistress. She is more than a little unpredictable, or at least it feels this way on Site5. While I realize that Apache is a web server, a computer who should be very logical, often times I notice very odd behaviour. Maybe it is the server setup, caching, or even traffic volume, I do not know. I do know that if you have some error in your htaccess file, the Apache server will then display a combination of ip addresses and host names. Once you fix the error, which no one can point out and there is no error message to go by, you will be back to only ip addresses.
