Ruby Mechanize Debug Request Headers

If you are trying to debug your headers:

Start listening on some port:

nc -kl 1234

Then just send a request to that port:

require 'mechanize'

agent = Mechanize.new
agent.get('http://localhost:1234')

Afterwards you will see all the headers sent to on the terminal screen where you'd ran nc command.
