title: Possibly Encrypted "a href" Links at TripAdvisor
body: <p>On <code>TripAdvisor.com</code> attraction pages, the link to the website of the attraction seems to be encrypted in some way. Here is an example:</p>
  
  <pre><code>&lt;span class="taLnk hvrIE6" onclick="ta.trackEventOnPage('AttractionContactInfo',
  'Website', 1755031, 1); ta.util.cookie.setPIDCookie(15190);
  ta.call('ta.util.link.targetBlank', event, this
  {'aHref':'LqMWJQiMnYQQoqnQQxGEcQQoqnQQbIIEJnISiCQQoqnQQeVsSVuWJQzZYUWJQpEcYGII26XombQQoqnQQQQoqnqgoqnQQQQoqnQQQQoqnQQQQoqnqgoqnQQQQoqnQQEVMIGVJIEV9pCyTptGiuQQoqnQQQQoqnxioqnQQQQoqnQQniaWJQzhY3mJnJUUJXomoAvoJJB', 'isAsdf':true})"&gt;
      Website
  &lt;/span&gt;
  </code></pre>
  
  <p>How is this link made and what might be the reason for doing so?</p>
