[squid-users] About "no_cache deny"

The Squid doc says that caching of specified domains can be prevented by
use of the "no_cache deny" directive. Specifically, it says that URLs with
the domain are "immediately removed from the cache". Can I get a little
clarification on what Squid actually does?

For example, I have this:

    acl clickthebutton dstdomain .clickthebutton.com
    no_cache deny clickthebutton

0. Is the URL really written to the cache then removed, as the description
says, or just not written to the cache to begin with?

1. Are clickthebutton.com URLs removed from memory as well from the on-disk
cache?

2. Is it possible to remove cached clickthebutton.com URLs that were
written before the "no_cache deny" ACL was instituted?

3. Is there a related mechanism in Squid for preventing the logging of the
no_cache URLs to access.log?

Thank you.
