iRule for Whitelist basepath

when HTTP_REQUEST {
    set uristring [string tolower [HTTP::uri]]
 
    switch  $uritring {
        "/test/blockeduri/" { 
            if { [IP::client_addr] equals x.x.x.x } {
                #allowed ip
            } else {
                #blocked - wrong IP
                 drop
            }
    }
    default {}
    }
}
 

Should be something along these lines. Though if you have several IP adresses to whitelist I recommend doing it as a data-group.
