<p>This page reports whether your browser is online or offline. It will detect
changes to the reported state and fire events when this changes. The
OnlineHandler acts as a wrapper around the HTML5 events <code>online</code> and
<code>offline</code> and emulates these for older browsers.</p>

<p>Try changing <strong>File -> Work Offline</strong> in your browser.</p>
