Multiple SSL domains to one Azure Cloud Service Site

Question

We have a web application running on Windows Azure Cloud Service at ourapp.cloudapp.net. We created a CName record from my.ourapp.com<

Answer 1

Just in case someone else needs help on this, there were two problems:

1. The SSL cert I was using wasn't chained correctly. If you get 3 certs from your provider, you need to install them correctly using the IIS and MMC. See here for more info.
2. The SNI article did work. The problem for us was the binding order. We ended up the following order:

As you can see we had to play around to get this to work but the following bindings meant that both domains would point to the same web application.

You will notice that we have added in my.ourapp.com twice - one with SNI enabled and an IP address and the other without. SNI does not work with IE on Windows XP - we added the last option as a default, non-SNI binding so our main domain would always work, even on IE & XP.

Hope that helps someone.
