title: How does HTTP download work?
body: <p>Let's say i want to download a file called example.pdf from  <a href="http://www.xxx.%D1%83%D1%83%D1%83/example.pdf" rel="noreferrer">http://www.xxx.ууу/example.pdf</a></p>
  
  <p>Probably, i send  GET request like this:</p>
  
  <pre><code>GET /example.pdf HTTP/1.1␍␊
   Host: www.xxx.yyy␍␊
   ␍␊
  </code></pre>
  
  <p>But what's next?</p>
  
  <p>How does exchange of http headers look like?</p>
