Let say you want to redirect user to some page then your operators are offline.

You can do that by adjusting your embed code and appending redirect url. E.g

<script type="text/javascript">
var LHCChatOptions = {};
LHCChatOptions.opt = {offline_redirect:'http://google.com'};

(function() {
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
var refferer = (document.referrer) ? encodeURIComponent(document.referrer.substr(document.referrer.indexOf('://')+1)) : '';
var location  = (document.location) ? encodeURIComponent(window.location.href.substring(window.location.protocol.length)) : '';
//po.src = '//demo.livehelperchat.com/index.php/chat/getstatus/(click)/internal/(position)/bottom_right/(hide_offline)/true/(department)/4?r='+refferer+'&l='+location;
po.src = '//demo.livehelperchat.com/chat/getstatus/(click)/internal/(position)/bottom_right/(check_operator_messages)/true/(top)/350/(units)/pixels?r='+refferer+'&l='+location;
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();
</script>
