How setup proxy to glue couchDB to Rails?

[Audrey Lee]

Hello nginx people,

Is it possible to use nginx to "glue" 2 types of servers into one?

I have a rails server running here:
  http://localhost:3000/rails/

And I have a couchDB server running here:
  http://localhost:5984/

I'd like to configure nginx so that it listens on 8080

I want any request directed at:
  http://localhost:8080/rails/
to be forwarded to
  http://localhost:3000/rails/
And I want all other requests to be forwarded to
  http://localhost:5984/

Have any of you done something like this?

Is nginx well suited for this or should I be learning about a true
proxy like squid or varnish?
