  <Valve
    className="org.apache.catalina.valves.RemoteHostValve"
    allow="*.mycompany.com,<A href="www.yourcompany.com" target=_blank>www.yourcompany.com</A>" />
  <Valve
    className="org.apache.catalina.valves.RemoteAddrValve"
    deny="192.168.1.*" />
</Context>

<Context path="/examples" ...>
  ...
  <Valve
    className="org.apache.catalina.valves.RemoteHostValve"
