I need to set up Rails as a sub-domain to another application. Are there any steps I need to take. Not sure how to get started.

i did not really workt with subdomain in rails. Why do you need actualy a subdomain? If you are working with more rails applications you could start it on the same server using diffrent ports. I don’t know if this was the answer to your question. Is that what you ment? ---

Handling subdomains or other protocols (e.g. https) in rails isn’t unsophisticated at all. But Dan W. recently released a rails plugin called «request routing» to simplify these solutions. To install the plugin type the following command: ruby script/plugin install [http://svn.vivabit.net/external/rubylibs/request\_routing](http://svn.vivabit.net/external/rubylibs/request_routing) The properties to differentiate are listed below: -subdomain -domain -method -port -remote\_ip -content\_type -accepts -request\_uri -protocol i found this post on a forum ---

Tux, thank you. I did look at Dan’s plugin and I believe it will help. The reason why I need Rails as a subdomain, is that another application (non Rails) is the front end (so to speak). However Rails is doing all of the database work. So, spcifically, what I think I’m lacking on in knowledge - 1- Does Rails sit in a subdirectory of the main app, like a subdomain typically would ? 2- Any special configurations for Rails ? 3- How about the app that will be making the calls, do I need some kind of redirects or just making the call to the subdomain should be enough ?

If all you are trying to do is make: [www.foo.com](http://www.foo.com) =\> your first app [bar.foo.com](http://bar.foo.com) =\> your second app You have several choices. If your first app is PHP (which I believe you said it was), then let Apache serve it directly using mod\_php, and proxy a port to your Rails app on a different port. Then set up Mongrel or Lighty to listen on that second port. If they are both Rails apps, it’s a snap: Use Pound to resolve the subdomains and proxy them to Mongrel packs running on different ports.

If they are both Rails apps, it’s a snap: Use Pound to resolve the > subdomains and proxy them to Mongrel packs running on different ports. I wish it was just Rails, but good information as well. There is much better information around on multiple Rails apps , then Rails + some other language. I saw the Pound stuff up on the wiki. Stuart
