It can. It's called URL re-writing and is generally a very bad idea in
the current web since the client and server each think they are
presenting resources for a different domain. If any part of the HTTP
transaction heaser, or HTML content or scripts or DOM tree of the client
is generated with the server's view of the domain things screw up
immediately.

Laziness is no excuse to break the Internet for the proxy users.

If you want users to bypass the proxy controls this easily, simply let
them past in the first place.

OR, provide them with the tools necessary to keep the list updated
instead of doing it yourself. You could have the list in a DB, an
external_acl_type helper to check it in real-time, a user-visible form
to add entries to the DB and a "unlist list" button on the block error page.

It would work far better having the browser configured to use a which
has a static IP and simply relays traffic to the main proxy. Proxy
chaining is what that is called.
