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
Windows Azure Websites run IIS. You can use URL rewriting to create rules to rewrite one URL to another.
Instructions:
Create a website in Windows Azure.
In the Scale section, select a web site mode of Shared or Standard and save changes.
In the Configure section, on the domain names group, add the old domain name (or names) and the new domain name and save changes.
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."
Upload your new website's contents to Windows Azure.
In the root of the new website, create a file named Web.config with a contents like this:
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".
For documentation refer to Using the URL Rewrite Module.
For examples refer to Redirect to new domain after rebranding with IIS Url Rewrite Module and IIS URL Rewrite – Redirect multiple domain names to one.
