r2239 r2240 698 698 request. A stored response is considered "fresh", as defined in <a href="#expiration.model" title="Freshness">Section 4.1</a>, if the response can be reused without "validation" (checking with the origin server to see if the cached response remains 699 699 valid for this request). A fresh response can therefore reduce both latency and network overhead each time it is reused. When 700 a cached response is not fresh, it might still be reusable if it can be freshened by validation (<a href="#validation.model" title="Validation">Section 4.2</a>) or if the origin is unavailable ( xref target="serving.stale.responses" />).700 a cached response is not fresh, it might still be reusable if it can be freshened by validation (<a href="#validation.model" title="Validation">Section 4.2</a>) or if the origin is unavailable (<a href="#serving.stale.responses" title="Serving Stale Responses">Section 4.1.4</a>). 701 701 </p> 702 702 <h2 id="rfc.section.1.1"><a href="#rfc.section.1.1">1.1</a> <a id="conformance" href="#conformance">Conformance and Error Handling</a></h2>
