    you can write iRule something below.

    when HTTP_REQUEST {
if { ([HTTP::host] equals "abc.com" or [HTTP::host] equals "xyz.com") } {
	if { [HTTP::uri] starts_with "/123/456/" || [HTTP::uri] starts_with "/cat/dog/" } {
	pool poo_A

	else { reject }
		} 
	}

     OR

    when HTTP_REQUEST {
	if { !([HTTP::host] equals "abc.com" or [HTTP::host] equals "xyz.com") && !([HTTP::uri] starts_with "/123/456/" || [HTTP::uri] starts_with "/cat/dog/") } {
	reject }
	}

Thank you Samir. I like the second option of yours and it seems to work.
