title: Get specific cookie from request headers (express)
body: <p>I came across an issue today with express, assume we set several cookies, when I use <code>request.headers</code> only one cookie is returned:</p>
  
  <pre><code>cookie: 'userSession=123'
  </code></pre>
  
  <p>for example, not only can't I use <code>request.headers.cookie</code> as it is unreliable (users can have several cookies set), but I can't parse it into a JSON object (this is invalid json) nor can I select this cookie specifically, which leads to a subquestion, is this how we get cookies from express response, through headers?</p>
