Rack::Process

Proxy to a rack application in a separate process.

An issue filed for pow piqued my curiosity. After itching, this is what I came up with.

You can't run multiple rails applications in the same process. Instead, we can load those applications in separate processes and compose them using Rack.

Here's a simple example config.ru which does just that:

require 'rack'
require 'rack-process'

run Rack::URLMap.new \
  "/first" => Rack::Process.new('/path/to/rails-app-1'),
  "/second" => Rack::Process.new('/path/to/rails-app2')

• @josh's excellent nack used by pow.
• @tpope for Ruby IO Mixins.
• Daniel J. Bernstein for netstrings, and @josh for nack's implementation.
