can web admins choose to prevent use?

I believe so, but only by blocking the proxy's IP addresses.

Web admins should use the no-cache HTTP header to prevent pages that shouldn't be cached from being cached. Any self-respecting proxy should follow this. A shift-reload (or equivalent) should force a page reload. Some proxys don't follow this.
The Pragma thing doesn't work on it's own. A web server needs to know how to pass it along to the HTTP headers. Some hosting providers don't do this.
