I am using a subdomain as a parameter to an ASP.NET MVC 4 application. It's working well.
Now I need to test my approach, so I have the application hosted on appharbor. It works well with subdomains here too. Our DNS registers are on Rackspace, but I have no control over it. Another guy is responsible for that. So, myapp.apphb.com can be accessed through myapp.com. Also abc.myapp.com is working as expected. I use abc as a parameter.
So, now I want abc.com to be mapped in those Rackspace DNS registers to abc.myapp.com
Is this possible at all? Can you explain to us how to do that? Will I have some problems with it? Anything that I should be aware of?
Please have in mind that I am newbie when it comes to DNS. And no experience with Rackspace.
