Thanks Enes -- Appreciate your help on this ...

 

if we choose to use code to allow the host with "abc.example.com" only .. will that include the header of "www. abc.example.com" or need to explicitly add it what that "and" statement would be ?

Hi TJ01,

It will not contain "www.abc.example.com". If want to match with www:

when HTTP_REQUEST {
	if { [HTTP::host] ne "abc.example.com" && [HTTP::host] ne "www.abc.example.com" } {
		log local0. "request dropped - Host: [HTTP::host] ClientIP: [IP::client_addr]"
		drop
		return
	}
}
