There is a script for this on CSS

ap-kal-httpcheck.

The script connects to a webserver on port 80 by default.It performs a GET on the specified page. If the WebString is returned, the service stays up. If anything fails, the service is marked down.

The syntax for this KAL is:

ap-kal-httpcheck \'WebSiteIP WebPage WebString [Port]\'

for e.g.

service web1

ip add 10.10.10.1

keepalive frequency 10

Keepalive type script ap-kal-httpcheck ?10.10.10.1 /index.html teststring?

active

Hope it helps
