I have single sign on enabled and to log off a user, I have a "Log Off" button link to the thisJSP:

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<jsp:scriptlet>
session.invalidate();

Cookie cookie=new Cookie("JSESSIONIDSSO", "");
cookie.setDomain(request.getHeader("host"));
cookie.setPath("/");
cookie.setMaxAge(0);
response.addCookie(cookie);
</jsp:scriptlet>
<c:redirect url="/" context="/" />
</jsp:root>

This causes the following exception in the server log:
