1. Add a CNAME entry for the sub-domain in the DNS hosting provider
I clicked the ‘Add Record’ link below, and points the sub-domain ‘ask’ to the Azure website ‘ask-scott.azurewebsites.net’, and ‘awverify.ask’ to ‘awverify.ask-scott.azurewebsites.net’
2. Configure the Azure Website
Next, I went to the Azure portal to configure my Azure website. I switched to the CONFIGURE panel of the ask-scott forum, and scroll down to the ‘domain names’ section.
Click ‘Manage domains’ and add ‘ask.scottge.net’ to the list.
After the changes are saved, the new sub-domain became live! http://ask.scottge.net.
