Bounces or redirects requests to missing static files. Partially inspired by http://menendez.com/blog/using-django-as-pass-through-image-proxy/

I.e. could be useful when you want to run the server with production database locally and have user uploaded content fetched transparently from production site.

Options: :mode - [ :off, :bounce, # returns 404 to any request to static URL, :fallback ] # any request to static path is redirected to :fallback_static_url :static_path_regex - Regexp which matches the path to your static files. Along the lines of the Capistrano conventions defaults to %r{/system/(audios|photos|videos)} :fallback_static_url - URL of the production site

Install via rubygems:

gem install rack-static_fallback

then, for Rails (any version which supports Rack) apps, add the following to your 'config/environments/development.rb'

require 'rack/static_fallback'
config.middleware.insert_after ::Rack::Lock,
                               ::Rack::StaticFallback, :mode => :fallback,
                                                       :static_path_regex => %r{/system/uploads},
                                                       :fallback_static_url => "http://myproductionsite.com/"

Aternatively, you should also be able to use the gem in Rack apps with:

use ::Rack::StaticFallback, :mode => :fallback,
                            :static_path_regex => %r{/system/uploads},
                            :fallback_static_url => "http://myproductionsite.com/"

in your 'config.ru' (this is untested so mileage may vary)
