  }
}

The statement [[string tolower [HTTP::uri]] contains "leisurelink" ] does not require the outer set of [ ].

The command [ [IP::client_addr] equals 10.0.0.0/255.0.0.0] is not valid. You appear to be missing the IP::addr command to make this work. [IP::addr [IP::client_addr] equals 10.0.0.0/255.0.0.0]

See how you go with that.
