title: How to make a HTTP request using Ruby on Rails?
body: <p>I would like to take information from another website. Therefore (maybe) I should make a request to that website (in my case a HTTP GET request) and receive the response. </p>
  
  <p>How can I make this in Ruby on Rails?</p>
  
  <p>If it is possible, is it a correct approach to use in my controllers?</p>
