Support the following protocol recommendation: "If a request includes the no-cache directive, it SHOULD NOT include min-fresh, max-stale, or max-age." http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.4 We address this by looking for no-cache and then filtering the above directives out if present.
