Code first, talks later.

Replace the “yourdomain” with your domain name and add it under the system.webServer section in the Web.Config, and that’s it.
Some people prefer www domain and some non-www. I personally prefer www URLs. One important point to remember is never to allow both accessible at the same time. Read my article REDIRECT NON-WWW URLS TO WWW URLS to know why. It will be better if you add the rule on the Web.Release.config with a slight modification. Read more about it on my article INSERTING REWRITE RULE IN RELEASE CONFIG.
