Robert,
Fantastic - exactly what I was looking for!
I've just downloaded an HTTP monitoring tool called "PagePoke" (perl) from
Freshmeat, will see how it goes. It's GPL so you could easily change to an
XML file format if wnated. Alternatively if you feel like hacking a little,
you could grab JMeter from java.apache.org and wrap a daemon around that?
(It's a very good multithreaded load tester)
Thanks,
Mike
