URL which is based on the net/shibboleth/idp/views/cas/logoutService.vm template. The template returns HTML which cannot be parsed as JSON by the onLoad() function as specified in <tt>propagate.vm</tt>, and thus a JavaScript error is catched, so the CSS class is changed to "failure". However, as the rendered template does a HTTP POST and finally loads a JSON document within the <iframe>, the onLoad() function is called again, and the CSS class is finally changed to "success".</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">A solution would be to identify the intermediate HTML page in the onLoad() function and just return from the function, leaving the CSS class "pending" untouched.</p> </td>
