  <web-resource-collection>
      <web-resource-name>Login Required</web-resource-name>
      <url-pattern>/delete.jsp</url-pattern>
      <url-pattern>/delete.do</url-pattern>
      <http-method>GET</http-method>
      <http-method>POST</http-method>
  </web-resource-collection>
  <auth-constraint>
      <role-name>admin</role-name>
