Good.

Yes, the ARGx use is correct now. I assume that when it's working, your
test harness actually displays the text 'QA-testHarness' in the page.

You want to check the web server logs on the machine running your test
harness. That's the server returning the 200 OK that nagios is properly
accepting as successful. You'll want to verify that the request is
actually for the host/port/url you think it is.

However, based on what you've shown above and your previous post, I
suspect that you have multiple copies of nagios running, one with an old
configuration and one with the new. Stop nagios and make sure it's
really stopped, then start again.
