304 Not Modified

Not Modified


The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource. This happens when the request method is a safe method, such as GET or HEAD, or when the request is conditional and uses an If-None-Match or an If-Modified-Since header.

The response must not contain a body and must include the headers that would have been sent in an equivalent 200 OK response: Cache-Control, Content-Location, Date, ETag, Expires, and Vary.
