I have a web site (Tulpep) app runing in AppHarbor.
The default domain in appharbor is http://tulpepwebsite.apphb.com/.
The site is running on ASP.NET MVC 4.5.
Is it possible to redirect the users if in some case they visit the *apphb.com domain to my custom domain?
I think it may be not possible because the redirection from my custom domain to my apphb.com domain is made by a DNS from www to tulpepwebsite.apphb.com
You can define a canonical hostname on AppHarbor.
