Sinatra not passing header with redirect

I have a simple Sinatra proxy, which when an endpoint is called, will redirect to another endpoint on the same Sinatra proxy.

When I make a request with a header, the proxy doesn't seem to pass this header through to the second endpoint when the request redirects in the first. This is my code:

    get '/first' do 
        # get the header from the request
      user开发者_如何学JAVAname = env['HTTP_USERNAME'] 
        # set the header for the response
      response['username'] = username 
      redirect '/second'
    end

    get '/second' do 
        # This doesn't exist when redirected from /first
    puts env['HTTP_USERNAME']

        # Here is a list of all headers
      env.each_key do |key|
        puts "KEY: #{key}  VALUE: #{env[key]}" unless key.nil?
      end

      "DONE"
    end

Any tips would be greatly appreciated.

Thanks


That is intentionally. redirect triggers an HTTP redirect, a new request will be fired. Also, passing on env values is done via modifying env, not response.

The main question is, what do you mean by header? Request header or response header? From your example I figure you mean request header, therefore response['username'] = username should be request.env['username'] = username. You could then replace redirect '/second' with request.path_info = '/second'; pass to do some sort of internal redirect. If you don't pass the value on to another Rack middleware/endpoint, you could also store the user name in an instance variable.

get '/first' do
  request.path_info = '/second'
  pass
end

get '/second' do
  puts request.env['HTTP_USERNAME']
  "DONE"
end
