RE: extension of ApplicationGateway

Hi Thorsten!

Ok, I have just checked in a build which provides a solution. From the
comments...

<p><b>csc_100603_1</b> - Modified ApplicationGateway so that there is a new
RESPOND_WITH_404
constant which defaults to false but can be overriden to true. If true,
rather than create
a generic HttpRequestEvent when a bad event is specified, simply return a
404 error.

What this means is that all you need to do is override this constant - the
easiest way to do that is via the object repository.xml file, like this:

    <object class="org.enhydra.barracuda.core.event.ApplicationGateway">
      <prop name="RESPOND_WITH_404">true</prop>
    </object>

That work for you? Please note that I haven't actually tested this, but I'm
pretty certain it works...if you could kindly update from cvs and give it a
spin to verify, I'd be most appreciative.
