One rather brute force way to get round this is to append a unique (per-session at least) id to the querystring of each page, which means that the page will be requested from the server rather than the cache. I believe this works in Opera as well as other browsers.
There is more to cache-control and expiring pages than meets the eye, do a search on it or read the rfc. Ultimately it is down to how user agents interpret those commands, and there is no substitute for testing...
