getRemoteHost returns null

[Will Glass-Husain]

Hi,

For some reason, getRemoteHost is returning null.  getRemoteAddr works fine.
I'm running Tomcat 4.0.4 with the AJP 13 connector:

    <Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
               port="8009" minProcessors="5" maxProcessors="75"
               acceptCount="10" debug="0"
                enableLookups="true"
/>


My understanding is that getRemoteHost should return the IP address if it
can't get the host.  But it seems to be doing neither.

Any ideas?

Thanks, WILL
