Please note the word "likely" - you wrote it yourself. The fact
that something results from a CGI script doesn't qualify for
immediate expiry. A proxy cache should always pay attention to the
Expires header, even if the URL contains a '?' and a search string.
There are CGI results lasting for years (at least).
