TldLength

Reconfigures ActionDispatch's TLD handling dynamically based on the request host, so you don't have to mess with config.action_dispatch.tld_length for cross-device testing using xip.io and friends

Heavily based on Tim Lucas' Gist.

Installation:

The simplest way to use Rack::TldLength is to use Bundler.

Add Rack::TldLength to your Gemfile:

gem 'tld_length'

Usage

Add the following line to your config/environments/development.rb:

config.middleware.use Rack::TldLength, /(x|n)ip\.io/, 5

And you're done!
