<h1>test the JSR223 interp stuff</h1>
Here are some simple tests.  Each script gets a value from the
request object, then set a value that can be referenced later in
the page.
<p>
For languages that have a notion of "printing to stdout", all output is
captured, and placed in the page.  Otherwise, the result of the script
can be placed in the page using the "result=true" attribute.
<hr>
<interp language="JavaScript" result=true>
  request.props.put("script.javascript", "hello");
  "Javascript! version= " + brazil_version + " port=" + props.getProperty("port");
</interp>
<hr>
<interp language=ruby>
  $request.props.put("script.ruby", "hello")
  puts "Ruby on port " << $request.props.get_property("port")
</interp>
<hr>
<interp language=php>
   <?php print ('PHP hello from port ' . $props->getProperty('port')); ?>
   <?php $rewrite_context->request->props->put('script.php','hello'); ?>
</interp>
<hr>
