Depends on your definition of a proxy server. If by proxy you mean as a
cache engine, then no, obviously not. But if you mean as a centralized
point of exit to the internet that is capable of hiding your private
network, then yes. By using TACACS+ or RADIUS, you can even authenticate
users. The PIX will prompt the user for a username and password on their
first try at getting to the net, then check that u/p with the authentication
server. Once the server respondes with that users authorization level the
user is granted/denied access to that service.
If by proxy, you mean as a URL filter, the answer is yes, by only in
conjunction with a third part piece of software like WebSense. All user
requests are first forwarded to the WebSense server and checked for the
policy of it. If it is acceptible, the request is then passed to the
Internet, but if it is denied the request is denied and either a custom page
can be returned to the user telling them it is a site that violates your
policy, or my favorite, returns a generic site error, making them believe
that the site is down.
