iRule to only allow traffic from 3 differents subnets

IheartF5, thanks for your answer. Just one more thing, do you think that something like this would work?

when HTTP_REQUEST { if {( [string tolower [HTTP::path]] ends_with "/xxx " ) and not ( [matchclass [IP::client_addr] equals $::xxx_allowed] ) } { HTTP::respond 200 content "URL Blocked" } }
