When I put up a new website in Azure I tend to run into the same problems. Pointing DNS to the azure website nets a lot of urls. I’ll have mydomain.com, www.mydomain.com, mydomain.azurewebsites.net, and http/https versions of all of them. When talking SEO, you generally don’t want duplicate ways to get to the same content. Luckily, this can be solved relatively painlessly with url rewrites in the web.config. I put together a quick reference to handle some of the scenarios.
