title: Google PageSpeed not updating cache
body: <p>I have google's pagespeed installed with nginx server installed following <a href="https://github.com/pagespeed/ngx_pagespeed" rel="nofollow">here</a>. I need to flush/delete the previous cached content but could not find a solution. On <a href="https://developers.google.com/speed/pagespeed/module/system#flush_cache" rel="nofollow">pagespeed site</a> its mentioned to use this command:</p>
  
  <pre><code>touch /var/ngx_pagespeed_cache/cache.flush
  </code></pre>
  
  <p>But I have no success with it. Thanks for any help.</p>
