RoR3 redirects not including RAILS_RELATIVE_URL_ROOT

Question

On my public-facing Apache2 server access to my Rails 3 app is via a sub-URI, like

https://www.myserver.com/myapp/controller...

that server is configured for reverse proxy to another Apache2 server hosting the Rails app via Passenger:

http://intranet.server.com/myapp

In my VirtualHost settings for the intranet server I have

SetEnv RAILS_RELATIVE_URL_ROOT "/myapp"

In my config/environments/production.rb file I uncommented the line

config.log_level = :debug

This way, the very first executing method in my app issues:

logger.debug { "The environment variable RAILS_RELATIVE_URL_ROOT is presently #{ENV['RAILS_RELATIVE_URL_ROOT']}" }

and sure enough, in the production log file you see:

The environment variable RAILS_RELATIVE_URL_ROOT is presently /myapp

However, the next line in the log is, which is obviously what the browser goes to:

Redirected to https://www.myserver.com/controller/action

I learned about this environment variable here on Stackoverflow, so that's one person for whom it worked, but one other person chimed it didn't to which another said it did. So with my experience, we're now at a tie. Am I missing something?

Answer 1

I figured out my error. The reverse proxy settings on the external server referenced just the hostname of the internal server and left off the path to my RoR3 app.
