[Zope] Logout with standard basic authentification

[Terry Kerr]

The problem with this is that the browser will not clear its cache of this
valid username/password unless the user clicks 'OK' on the login dialog box
that pops up.  If the user clicks 'Cancel' then the browser assumes that
the user doesn't want to change the username/password, and keeps the
existing one in cache, hence, a reload of the page will be successfull.

Does anyone know of any tricks to get around this?
