A request header is an HTTP header that can be used in an HTTP request, and that doesn't relate to the content of the message. Request headers, like Accept, Accept-*, or If-* allow performing conditional requests; others like Cookie, User-Agent or Referee precise the context so that the server can tailor the answer.
The if modified since header is an HTTP header that is sent to a server as a conditional request. If the content has not changed the server responds by providing only the headers with a 304 status code.
The If-Modified-Since header is used to specify the time at which the browser last received the requested resource. The If-None-Match header is used to specify the entity tag that the server issued with the requested resource when it was last received.
14.1 Accept The Accept request-header field can be used to specify certain media types which are acceptable for the response. Accept headers can be used to indicate that the request is specifically limited to a small set of desired types, as in the case of a request for an in-line image.
304 Not Modified is an HTTP status code that is returned to the client when the cached copy of a particular file is up to date with the server. ... When a request is made from the browser for the same file again, the if modified since header is sent to the server.
The Last-Modified response HTTP header contains the date and time at which the origin server believes the resource was last modified. It is used as a validator to determine if a resource received or stored is the same. Less accurate than an Tag header, it is a fallback mechanism.
