As I read the documentation for excalibur.monitor.StreamResource, there is written:
"It can notify the change as soon as the Writer or OutputStream has been closed."
But that is the point: I want to push the bytes to the browser (or the next component
in the pipeline) even if the OutputStream is still open.
Another Question would be: How to configure. Like This:
<monitor>
<thread priority="5" frequency="10000"/>
<init-resources>
<resource key="...<.W.H.A.T. .H.E.R.E.?>..."
class="org.apache.avalon.excalibur.monitor.StreamResource"/>
</init-resources>
</monitor>
