404, 304, 301, and everything else that isn't 200, 202, or 500

For my next newb question: I have a proxy set up that looks like this:

        <sequence name="getURL" onError="myFault">
                <!-- big script that sets the message To: was here-->
                <send>
                        <endpoint>
                                <default format="get" trace="enable"/>
                        </endpoint>
                </send>
        </sequence>

        <sequence name="myFault">
                <log level="full"/>
                <send/>
        </sequence>
        
        <proxy name="feed" transports="http">           
                <target inSequence="inSeq" outSequence="setMessageType" 
faultSequence="myFault"/> 
        </proxy>        

The proxy gets out to the message destination just fine and if the server at 
the destination sends a 200 OK all is well. However, if the server comes back 
with a 'non-ok' code like 304, it gets logged that an unexpected http status 
was recieved, but the myFault sequence never runs (so far as I can tell - 
nothing is logged, anyhow). Did I miss something here?

Thanks again,
