title: How to use nofollow link in script tag
body: <p>This is my script code:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;script type="text/javascript" src="//example.com/js/infolinks_main.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I want to make crawler not to follow or index <code>example.com/js/infolinks_main.js</code>.</p>
  
  <p>How can I do this task? I have robots.txt in my root, but that URL is an external URL.</p>
  
  <p>NB: I do not want to use <code>iframe</code>.</p>
