asp.net - Azure Website 301 Redirect - Where Do I Put It?

Question

I want to direct some of my other domains to my primary domain which is hosted at a Windows Azure website.

(For the sake of those that find working with CNAME's and DNS a little "foggy" (like I did) I'm going to layout the details.)

I have the domain www.myDomain.com correctly resolving.

I now want to point www.myOtherDomain.com to www.myDomain.com

At my registrar I have created a CNAME to point
www.myOtherDomain.com to myInternalAzureSite.azurewebsite.net
and then successfully configured it in the in the Azure Website domain manager tool.

Now, when I enter www.myOtherDomain.com into a browser I get the proper web page at www.myDomain.com, however, the address in the browser is still www.myOtherDomain.com not www.myDomain.com as desired.

I understand the two most desirable ways to accomplish this are either:

1. Forward myOtherDomain.com (which costs $ at some registrars)
2. Do a 301 permanent redirect

If I have all that correct, I have found many suggestions of HOW to do the 301 redirect, however, I can't seem to figure out WHERE to actually put the redirect?

Windows Azure Websites run IIS. You can use URL rewriting to create rules to rewrite one URL to another.

Instructions:

1. Create a website in Windows Azure.

2. In the Scale section, select a web site mode of Shared or Standard and save changes.

3. In the Configure section, on the domain names group, add the old domain name (or names) and the new domain name and save changes.

4. In your domain registrar or DNS provider for the old domain and the new domain, change the DNS records to point to the new Windows Azure Website. Use a "CNAME (Alias)" record and point it to the website's domain on Windows Azure, like this: "mywebsite.azurewebsites.net."

5. Upload your new website's contents to Windows Azure.

6. In the root of the new website, create a file named Web.config with a contents like this:

   <?xml version="1.0" encoding="utf-8" ?>
   <configuration>
       <system.webServer>
           <rewrite>
               <rules>
                   <rule name="Redirect old-domain to new-domain" stopProcessing="true">
                       <match url=".*" />
                       <conditions>
                           <add input="{HTTP_HOST}" pattern="^www.old-domain.com$" />
                       </conditions>
                       <action type="Redirect" url="http://www.new-domain.com/{R:0}" redirectType="Permanent" />
                   </rule>              
               </rules>
           </rewrite>
       </system.webServer>
   </configuration>
   

7. Verify that any request to "http://www.old-domain.com/path?query" will receive a "301 Moved Permanently" response with a Location header for "http://www.new-domain.com/path?query".
