Applying a health monitor with DNS returned IP address

Hi,

you can try with LB_FAILED event!!

when HTTP_REQUEST {
    if {[HTTP::uri] starts_with http} { HTTP::uri [findstr [HTTP::uri] [HTTP::host] [string length [HTTP::host]]} 
   set ips [RESOLV::lookup -a [HTTP::host]]

    Check if the first list element was empty
   if {$ips eq ""}{
       Input wasn't an IP address, take some default action?
   } else {
       Select the IP 
      node [lindex $ips 0]
   }
}

when LB_FAILED {
     The node timed out... 
}
