Exactly.  In fact, for security reasons you may want to disable incoming 
ICMP echo requests.  Remember, deny everything and only allow those 
services you are specifically using.  Since you care that the webserver is 
up, there's no need to ping.

If you insist on using bash instead of perl, could you have the system run 
a wget command for the index page and then parse the result?
