gbuesing / rack_tap.rb
Created June 13, 2013 15:54
# Middleware to tap into request so that you can provide an alternate response depending upon request conditions.
#
# Supplied block should return a Rack-compatible response, or nil/false to pass on handling of the request.
#
# Example:
#
# use Rack::Tap do |env|
# if Rack::Request.new(env).host == 'admin.myapp.com'
# [301, {'Location' => 'http://www.myapp.com/admin'}, []]
# end
