IIS: Redirect a domain such as xoc.net to www.xoc.net

Let's suppose that you have a web site http://www.xoc.net and you want http://xoc.net to do a client-side 301 error redirect to the http://www.xoc.net site. This is useful in several ways:

1. The client's browser will always show http://www.xoc.net, not http://xoc.net.
2. Listings in a search engine will always show http://www.xoc.net.

To perform the redirect, suppose that the content for www.xoc.net comes from c:\inetpub\www-xoc-net:

1. Open Internet Services Manager and create a web site for xoc.net. Make the content directory for the site be the same directory, c:\inetpub\www-xoc-net, as www.xoc.net.
2. Test getting content from http://xoc.net. This should work, but won't redirect yet.
3. Select the xoc.net web site in Internet Services manager and enter the properties.
4. In the Home Directory tab, change the option button "When connecting to this resource the content should come from" to "A redirection to a URL".
5. Specify the URL as http://www.xoc.net.
6. Check the checkbox that says "A permanent redirection for this resource."
