Rack::HttpTraceRejector

Automated security audits getting you down? Pesky "you need to block HTTP TRACE" requests showing up in tinfoil, or even worse, PCI audits, and because you're on Heroku without an NGinx configuration in sight, you don't know how to respond?

rack-http_trace_rejector is here to help. While this is a fairly simple patch to make on your own (check the source), bundling it up with a few tests was a big benefit to our team across 2 projects, and I figured the same might be true elsewhere.

Add this line to your application's Gemfile:

gem 'rack-http_trace_rejector'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-http_trace_rejector

module YourApp
  class Application < Rails::Application

    # Rails 3/4
    config.middleware.insert_before 0, "Rack::HttpTraceRejector"

    # Rails 5
    config.middleware.insert_before 0, Rack::HttpTraceRejector
  end
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
