To check whether your user name has been granted a particular role,
enter it here:
<form method="GET" action='<%= response.encodeURL("index.jsp") %>'>
<input type="text" name="role" value="<%= util.HTMLFilter.filter(role) %>">
<input type="submit" >
</form>
<br><br>

To add some data to the authenticated session, enter it here:
<form method="GET" action='<%= response.encodeURL("index.jsp") %>'>
<input type="text" name="dataName">
<input type="text" name="dataValue">
<input type="submit" >
</form>
<br><br>

<%
  String dataName = request.getParameter("dataName");
  if (dataName != null) {
    session.setAttribute(dataName, request.getParameter("dataValue"));
  }
%>
<p>The authenticated session contains the following attributes:</p>
<table>
<tr><th>Name</th><th>Value</th></tr>
<%
  Enumeration<String> names = session.getAttributeNames();
  while (names.hasMoreElements()) {
    String name = names.nextElement();
%>
<tr>
  <td><%= util.HTMLFilter.filter(name) %></td>
  <td><%= util.HTMLFilter.filter(String.valueOf(session.getAttribute(name))) %></td>
</tr>
<%
  }
%>
</table>
<br><br>

If you have configured this application for form-based authentication, you can
log off by clicking
<a href='<%= response.encodeURL("index.jsp?logoff=true") %>'>here</a>.
This should cause you to be returned to the login page after the redirect
that is performed.
