change rails environment regarding to request header

Question

I'm pretty new in rails and I would like to ask different database regarding to the origin of the request.

Something like :

http://localhost:80     env: production    database: production
http://localhost:8080   env: development   database: development
http://localhost:8081   env: test          database: test

I already have my three environments defined. I just want to switch !

According to this post, in my application.rb I could adapt

Rails.env = ActiveSupport::StringInquirer.new('production')

to

# application.rb
if request.headers['HTTP_ORIGIN'] == 'http://localhost:80'
    Rails.env = ActiveSupport::StringInquirer.new('production')
elsif request.headers['HTTP_ORIGIN'] == 'http://localhost:8080'
    Rails.env = ActiveSupport::StringInquirer.new('development')
elsif request.headers['HTTP_ORIGIN'] == 'http://localhost:8081'
    Rails.env = ActiveSupport::StringInquirer.new('test')

but it seems I haven't access to method headers :

C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.13/lib/rails/railtie/configurable.rb:30:in `method_missing': undefined method `request' for #<App::Application:0x3e9c088> (NoMethodError)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

I don't really see why you would want to do this, but how about starting three servers instead?

RAILS_ENV="production" rails s -p 80
RAILS_ENV="development" rails s -p 8080
RAILS_ENV="test" rails s -p 8081

Thanks for your response svoop. I would prefer have just one running server which dispatch requests instead of three instances. That's why I wanted to programatically switch environment. – Sylvain Feb 02 '14 at 10:32
I'm not sure this can be done at all since the different environments usually use very different settings e.g. for caching models or handling the asset pipeline. – svoop Feb 03 '14 at 18:59
