Slightly reformatted, and reference added:
Note: RFC 2616 ([RFC2616], Section 13.9) required that caches do
not calculate heuristic freshness for URLs with query components
(i.e., those containing '?'). In practice, this has not been
widely implemented. Therefore, servers are encouraged to send
explicit directives (e.g., Cache-Control: no-cache) if they wish
to preclude caching.
