History
Albert Engelbrecht d3c40ffb1f Fix Tempfile reference being returned as nil 
This PR fixes the issue of files being uploaded from users having
the params[:file][:tempfile] being returned as `nil`, rather than
an instance of Tempfile like it should be.

PR fixes #90, and shamelessly stolen from #91.

README.md

You should use protection!

This gem protects against typical web attacks. Should work for all Rack apps, including Rails.

Usage

Use all protections you probably want to use:

# config.ru
require 'rack/protection'
use Rack::Protection
run MyApp

Skip a single protection middleware:

# config.ru
require 'rack/protection'
use Rack::Protection, :except => :path_traversal
run MyApp

Use a single protection middleware:

# config.ru
require 'rack/protection'
use Rack::Protection::AuthenticityToken
run MyApp

The instrumenter is passed a namespace (String) and environment (Hash). The namespace is 'rack.protection' and the attack type can be obtained from the environment key 'rack.protection.attack'.
