Example of a simple Rack middleware for scrubbing your Rack headers of sensitive information.
class Rack::SecureHeaders
def initialize(app, options = {})
@app, @options = app, options
end
def call(env)
response = @app.call(env)
# [status, headers, response] = response
# Uncomment any of the following that make sense for your application:
# response[1].delete "X-Runtime"
# response[1].delete "Server"
# response[1].delete "X-Rack-Cache"
response
end
end
# MyApp::Application.configure do
# config.middleware.insert_after(Rack::Lock, Rack::SecureHeaders)
# end
