You can also use NBAR. See below an example that drops You Tube traffic but you can modify it to suit your needs

Class-map: YOUTUBE (match-all)

      24390 packets, 21832290 bytes

      30 second offered rate 494000 bps, drop rate 0 bps

      Match: protocol http host "*youtube.com*"

      Queueing

      queue limit 64 packets

      (queue depth/total drops/no-buffer drops) 0/0/0

      (pkts output/bytes output) 24390/21832290

      bandwidth 40% (226000 kbps)

as u see  . its only making traffic  494000 bps
