How do I get the naked domain for my site that is typed into a browser (example.com) to automatically redirect to www.mywebsite.com. Would this be done on the internal IIS web server or through the registration service DNS settings? I use Register.com and I tried asking their technical support, but they did not answer my question with a usable solution. 
Should I use IIS or my DNS provider to redirect my naked domain to its www version?
