Rails running as sub domain: Help please

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.
Please help

TIA

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 Webb 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

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 => your first app
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.

Excellent, great information, very much appreciated.

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.
