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:

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

Skip a single protection middleware:

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

Use a single protection middleware:

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