title: Default browser cache expiration period for text/html
body: <p>In case there's no cache expiration related headers (except <code>Date</code>, <code>Last-Modified</code> and <code>ETag</code>) in an HTTP response what would be the expiration period for a resource if its <code>Content-Type</code> is text/html?</p>
  
  <p>Does it depend on the browser?</p>
