title: How do I set the request headers using Reqwest?
body: <p>I need to make a GET request to a website with a cookie using the Reqwest library. I figured out how to send a GET request:</p>
  
  <pre><code>let response = reqwest::get("http://example.com")?;
  </code></pre>
  
  <p>How do I send the same request but adding some custom headers?</p>
