Thanks to everyone who has replied so far. Actually I do want to be
able to respond to different protocols, not just http, for both local
and network resources. Unfortunately neither
open location "some random string"
nor
do shell script "curl some random string"
actually returns an error on my system (the first one returns nothing,
the second returns an empty string), and they both just fail silently
if I wrap them in Steve's try block.
Not really a big deal, I was hoping I could make my script beep if it
tries to open an invalid url, but I guess I can live with it just
failing silently.
Mark mentioned a syntax check, which would be better than nothing. Is
there a recipe you could point me to?
Thanks,
Michael

basically just make stuff up and try to make it sound plausible.
