Rack::Header

Rack Middleware for overriding and adding additional HTTP response headers

Installation

Add this line to your application's Gemfile:

gem 'rackheader'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rackheader

Usage

# config.ru
require 'rackheader'
require 'rack/lobster'

use Rack::Header, 'Access-Control-Allow-Origin' => '*', 'Foo' => 'Bar', 'Biz' => 'Baz'
run Rack::Lobster.new

$ rackup config.ru

HTTP_* environment variables

In addition to specifying static headers in your application config, you can also set headers using environment variables.

For example, if you want to set the X-Robots-Tag only in certain environments, you can add the HTTP_X_ROBOTS_TAG environment variable.
