Hi, I’m having little problem getting my idea to work, would be very thankful if you could help me. I have one Ruby on Rails application sitting on server, and multiple subdomains, pointing to the same server/app. For example: > **[MainServer.com is for sale | HugeDomains](https://www.hugedomains.com/domain_profile.cfm?d=mainserver.com)** > > 100% satisfaction guaranteed. Hassle-free shopping. We help you find the right domain name. [user1.mainserver.com](http://user1.mainserver.com) > **[MainServer.com is for sale | HugeDomains](https://www.hugedomains.com/domain_profile.cfm?d=mainserver.com)** > > 100% satisfaction guaranteed. Hassle-free shopping. We help you find the right domain name. I want to have exactly the same app and exactly the same routes on all, except that I want to map root of [mainserver.com](http://mainserver.com) to different controller than other. For example: [mainserver.com](http://mainserver.com) =\> MainController [user1.mainserver.com](http://user1.mainserver.com) =\> UserController [user2.mainserver.com](http://user2.mainserver.com) =\> UserController Any ideas how can I do it using Rails routes? Or possibly URL rewrite in Apache proxy? I am also considering different approach - I will have 2 applications running, and share part of code (models, some base controllers), and map main web page to different instance than all other subdomains. Thanks and best, H.
