+1

Plus the "Pragma" header for ancient clients, if you want.

This is how we do it:

        Header set Cache-Control "no-cache, no-store, must-revalidate"
        Header set Pragma "no-cache"
        Header set Expires 0

Make sure you don't overdo this... if you have .css, .js files, etc.
that *should* be cached, don't let this apply to them.
