| No, because a response from a server doesn't mean it's serving anything - just means it's on and has a valid network connection.
For example:
mini:~ steve$ ping -c1 Mx01.bis.eu.blackberry.com PING mx01.bis.eu.blackberry.com (216.9.253.32): 56 data bytes 64 bytes from 216.9.253.32: icmp_seq=0 ttl=240 time=102.340 ms
--- mx01.bis.eu.blackberry.com ping statistics --- 1 packets transmitted, 1 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 102.340/102.340/102.340/0.000 ms
mini:~ steve$ curl -m10 Mx01.bis.eu.blackberry.com curl: (7) couldn't connect to host curl: (7) couldn't connect to host
It responds to ping but won't give me any data

try on error display dialog "No a valid URL" end try
If curl can't resolve the url it returns an error which AppleScript's try statement can catch.
