You can't 'ping' a URL. You can ping an IP address or properly qualified
domain name and this simply tells you if the machine/Internet appliance has
a network interface up and listening at that address.
Verifying that a URL is live (e.g. not returning a 404) is a bit more
tricky.
You could use CFHTTP and parse CFHTTP.FileContent for 404 (or other status
codes) to verify that the link is live, however, I would caution you in
doing so if the site you are building will receive heavy traffic (500K hits
a day or more depending on the average latency between your server and the
URLs to be checked).
Also, you might want to look into CFX_HTTP (someone please correct me if I
am wrong), as it is more robust than the built-in Allaire tag.
HTH!

Subject: PING to check URL
I can't find any documentation on using the PING command to check for a
valid URL. The alternative is to force my users to do it, when all I
want is to check its validity before allowing them to enter it on my
site.
Any thoughts?
TIA,
