You can create your own logout page and configure Identity Server to use it. To do this, you need to modify the Identity Server logoutSuccess_latest.jsp.
logoutSuccess_latest.jsp is called in a frame from nidp_latest.jsp. You can modify the file to display what you want or to redirect the user to your custom page. One way to provide redirection is to replace the information in the <body> element of the file as follows:
<body>
<script language="JavaScript">
top.location.href='http://<hostname/path>';
</script>
</body>
Replace the <hostname/path> string with the location of your customized logout page.
For information about how to modify a file, see Modifying Configurations.
IMPORTANT:Save a copy of your modified logoutSuccess_latest.jsp file. You will need to restore this file after you upgrade Identity Server.
