Contrived example:
class WelcomeController < ApplicationController
def first
logger.debug "REFERRER: #{request.referrer}"
logger.debug "REQUEST_URL: #{request.request_uri}"
redirect_to :action => :second
end
def second
logger.debug "REFERRER: #{request.referrer}"
logger.debug "REQUEST_URL: #{request.request_uri}"
redirect_to :action => :index
end
def index
end
end
So, I open a new tab and go to localhost:4000/welcome/first -- Here''s
the dev log output:
Processing WelcomeController#first (for 127.0.0.1 at 2010-08-23

"controller"=>"welcome"}
Completed in 70ms (View: 53, DB: 5) | 200 OK [http://localhost/]

In the second processed request (WelcomeController#out) -- why is the
referrer "/" and not "/welcome/first" ??
Ultimately I need to know inside of #second that I''m coming from
#first -- given that it was redirected. Any suggestions?
