title: Passing in headers to a remote request
body: <p>I have an HTTP GET request in Wordpress that looks like this: </p>
  
  <pre><code>$remote = vip_safe_wp_remote_get($api_base . "get.json?genre=" . $genre, false, 1, 3)
  </code></pre>
  
  <p>works fine, but I now need to pass in a couple of headers that look like this:</p>
  
  <pre><code>apikey: [key]
  authtoken: [token]
  </code></pre>
  
  <p>How can I pass these in? I've tried doing $headers = array() with the arguments passed in as key value pairs, but that returns an HTTP 503 error. The service works when I try to access it from the command line with cURL. </p>
