title: How to escape two forward slashes in Ruby Regex
body: <p>I'm trying to make a regex which finds the domain name using Ruby, so I tried this:</p>
  
  <pre><code>(?&lt;=.*/).(?=.*/)
  </code></pre>
  
  <p>On Rubular I always see this error message: <code>Forward slashes must be escaped.</code></p>
  
  <p>How do I solve this?</p>
