This is one of the things that has interested me for awhile, and I know that the service I am developing would greatly benefit from this.Various sites (Ning, Tumblr, Wordpress, etc) allow users to point their own domain at the site , where it is automatically configured to redirect to their own personal space within the service. What do I need to do to achieve this for my own uses? What type of environment is best optimized for this sort of functionality? And are there any serious risks I need to be aware of when attempting this?
How to allow custom domains from end-users?
