Control as in the ability to select exactly what modules your web-server is using, the control to set up your web-server for the exact load you want and the control to have your web-server act different from the norm.

I like how you compare IIS's MAIN config file with one of Apache's policy config files. The main apache configuration file makes IIS's look silly.

Actually you CAN do that with Linux fyi. But by default that is not how Apache is produced and or runs. Making it more portable as well. Try linking IIS into a groupwise system... go ahead! I'm waiting...
