check_http_curl.sh
This script connects to a site via curl and searches for a string in the web page.
If the string is not found it throws out an error and Nagios exit is set to 'critical'.
Save plugin in $USER1$ dir, in my case (Ubuntu 12.04) it is:
/usr/lib/nagios/plugins
and make it executable.

Command definition:

/etc/nagios3/commands.cfg:
...
# Check HTTP
define command{
command_name check_http_curl
command_line $USER1$/check_http_curl.sh $HOSTNAME$ $HOSTNOTES$
}

Hosts definition:
$HOSTNOTES$ is the string that the plugin will search in the web page source.
