title: Retrieve SSL Certificate with Zend Http Request and Response
body: <p>I'm trying to connect to a third party API and I'm using the Zend 1.7.0 framework to access it.  To authenticate, I have to first check an SSL certificate returned from a URL.  This is what I'm doing in my code.</p>
  
  <pre><code>$client = new Zend_Http_Client($url);
  $response = $client-&gt;request('GET');
  </code></pre>
  
  <p>The response is always OK, and when I navigate to '$url' I can see the certificate if I click on the lock in the bottom right corner of my browser window.</p>
  
  <p>Is there a way to access the certificate's owner, expiration date and other properties via the response object?  Do I have to do anything special to the request before sending it to obtain the information about the certificate?</p>
