AFAIK

Since you can block web msn by blocking signatures, and Cisco firewalls are not application layer devices, this is not possible with Cisco firewall alone.

You can do this easily with Checkpoint

SmartDefense which is integrated into

Checkpoint firewall. It's so easy even

cavemen can do it.

thanks but as you can understand I am asking for pix configuration...

I work with both Checkpoint and Cisco Pix, and

what you're asking can not be done with Cisco

Pix. Pix lacks the plugg-in module for these

features. Checkpoint can take care of this

via SmartDefense. Perhaps this can be done

with ASA with an IPS plugg-in module.
