Blocking Adobe Flash or streaming of Youtube video

[exchange1]

I have a Cisco 1811 with IOS Firewall software, I wish to block Adobe Flash to ensure my users will not be able to watch/stream videos from Youtube. I don't want to block the web site but block the watching of the videos. Can anybody help out?

Hint:

I tried this:

ip inspect name firewall http java-list 99 alert on audit-trail on timeout 10

Access-list 99 blocking the youtube website

[cisco24x7]

The idea here is to make it so slow that it is practically to view youtube video. Here is what I did:

class-map match-any cciesec

match protocol http url "*.youtube.com*"

policy-map cciesec

class cciesec

set ip dscp cs4

police 8000 conform-action transmit exceed-action drop violate-action drop

interface g0/0

service-policy input cciesec

This way watching video on youtube will be very painful.

Does that help?
