    A couple of ways.

    1. Get a proxy server that can integrate with the PIX to block traffic via keywords/urls or something like websense/ISA that are specific to the job.
    2. Create an acl that blocks the IP addresses of the sites you want to block.
    3. use your internal DNS servers to have local zones for the domains you want to block and set the A records for www to so they fail.
    4. Put blocks on them through exceptions in your IE browser.

    I know they are not all changes to your PIX but at least it gives you some options.

    Just to add to Keith's suggestions -
    There is absolutly no mechanism on the pix itself to do that. Period.
    You must use some other 3rd party product like WebSense, iPrism, BlueCoat or other web filtering product.
    I really like the iPrism product

    A workaround is to use bogus DNS entries for the domain, but I suggest using an unused local IP address instead of I've found that it just works better for some reason.
