title: Fetch large data using multiple requests
body: <p>My front-end is a Rails application, and my backend is a Padrino application.</p>
  
  <p>I want to fetch a large amount of CSV data from the backend. Doing makes the HTTP request timeout in the browser.</p>
  
  <ol>
  <li>I can not query the backend again and again, because each time it will generate the same data, there is no concept of offset and limit records.</li>
  <li>I tried sending directly from the backend to LB but it is not working for me.</li>
  </ol>
  
  <p>To summarize, an array of 10000k rows is generated to be sent to the UI or downloaded in a streaming fashion.</p>
