title: Strange domains in mod_pagespeed cache folder
body: <p>About a year ago I have installed mod_pagespeed on my VPS server, set it up and left it running. Recently I was exploring files on my server, went to pagespeed cache folder and discovered some strange folders.</p>
  
  <p>All folders usually named this way <code>,2Fwww.mydomain.com</code> or <code>,2F111.111.111.111</code> for IP addresses. I was surprised to see some domains that does not belong to me, like:</p>
  
  <pre><code>24x7-allrequestsallowed.com
  allrequestsallowed.com
  m.odnoklassniki.ru
  www.fbi.gov
  www.securitylab.ru
  </code></pre>
  
  <p>It looks like something dodgy is going on, was my server compromised, is there any reasonable explanation?</p>
