title: How to make async http request in rails
body: <p>In my rails app, I need to make a http request to 3rd party service, since http request is synchronous, sometimes it takes more than 20 seconds to get response back from them.</p>
  
  <p>I just push some data to that service, I don't care about what the response will be, so I want to make the request asynchronous, so my code will continue execution and not been blocked.</p>
  
  <p><em>How could I do it in ruby?</em></p>
