Restrict the HTTP access by ip address in data group

I want to restrict the access to the Web server by iRule with data group. There is a data group "testclient".

I made irules(with some restriction) like below. When the client ipaddress in "testclient" accesses, can it access to the server in pool A?

when HTTP_REQUEST {

if { [HTTP::header exists "X-True-IP"] } { set clientip [HTTP::header "X-True-IP"] } else { set clientip [IP::client_addr] }

set uri [ string tolower [HTTP::uri]]

if {([matchclass [IP::client_addr] equals $::testclient])}{ pool A } else { pool B } }
