I am not sure if this is an iis setting or if this is a domain hosting setting. but when I do something like example.org it will go to my site but if I just type in chrome example.org(http://example.org/) it does not work.
I tried to add in namecheap another cname with "*" pointing to my DNS name of my vm.
I have in namecheap
A Record: @ | ip address
Cname: * | websites721.cloudapp.net
Cname: www | websites721.cloudapp.net
