Help! Restrict usage of tcp port 80

[ignorante]

Hi,
Hope you can help me with this issue. I have a Pix 515UR with software version 6.1.3 and a router Cisco 3620 for the connection to my ISP. I need to resolve the next problem:
Is there a way to prevent port tcp 80 being used to for anything different to http? In other words, i want to deny the use of streamming audio or other apps that use port tcp 80. Maybe this is impossible to block, but any help will be welcome.
Thanks!

HI.

You can do this with a transparent or standard proxy server.
This will probably require additional hardware and software purchase, but is the best solution that I know of.

I've used a PacketShaper from Packeteer to do this. It works very well at blocking 'nuisance' protocols.
