<p class="MsoNormal">That makes sense. Particularly given that all post_logout_redirect_uri should be pre-registered and are compared byte-for-byte, leaving no place to, e.g., add query-string arguments to customize the behavior upon redirection. So yes, there
should be a 'state' parameter.<o:p></o:p></p>
