I would define a URL check template like so:

define service{
        name                            url-service
        active_checks_enabled           1
        passive_checks_enabled          1
        parallelize_check               1
        obsess_over_service             1
        check_freshness                 0
        notifications_enabled           1
        event_handler_enabled           1
        flap_detection_enabled          1
        failure_prediction_enabled      1
        process_perf_data               1
        retain_status_information       1
        retain_nonstatus_information    1
        register                        0
        notification_options            w,u,c,f,r
        servicegroups                   url,notifications
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              4
        normal_check_interval           2
        retry_check_interval            1
        contact_groups                  admins
        notification_interval           10
        notification_period             24x7
        }

And then follow that with a bunch of short checks.

define service{
        use                             url-service
        host_name                       foo.looksmart.com
        service_description             http check
        check_command                   check_url!/foo/bar/weeeeee
}

define service{
        use                             url-service
        host_name                       bar.looksmart.com
        service_description             http check
        check_command                   check_url!/bar/foo/weeeeee
}

define service{
        use                             url-service
        host_name                       weeeeee.looksmart.com
        service_description             http check
        check_command                   check_url!/weeeeee/query?foo=bar
}
