IRule to block URL/URI from Data Group

Hi kgaigl , 

this should work. Note that I'm not putting URI in lowercase so /login and /LOGIN will require two different matches (they would be two different URLs indeed anyways) 

when HTTP_REQUEST {
 set req "[string tolower [HTTP::host]][HTTP::uri]"
 if {[class match $req eq unallowed_datagroup]}{ HTTP::respond 403 }
}

ltm data-group internal unallowed_datagroup {
    records {
        www.somesite1.org/login { }
        www.somesite2.org/member { }
        www.somesite2.org/login { }
    }
    type string
}
