It is a means for the browser to tell the server and any intermediate caches that it wants a fresh version of the resource.This section defines the syntax and semantics of all standard HTTP/1.1 header fields.This can be used when a user agent or firewall prevents PUT or DELETE methods from being sent directly (note that this is either a bug in the software component, which ought to be fixed, or an intentional configuration, in which case bypassing it may be the wrong thing to do).Implemented as a misunderstanding of the HTTP specifications.(The word “referrer” has been misspelled in the RFC as well as in most implementations to the point that it has become standard usage and is considered correct terminology)The transfer encodings the user agent is willing to accept: the same values as for the response header field Transfer-Encoding can be used, plus the "trailers" value (related to the "chunked" transfer method) to notify the server it expects to receive additional fields in the trailer after the last, zero-sized, chunk.

The port number may be omitted if the port is the standard port for the service requested. Only perform the action if the client supplied entity matches the same entity on the server.

Notice that no-cache is not instructing the browser or proxies about whether or not to cache the content.

It just tells the browser and proxies to validate the cache content with the server before using it (this is done by using If-Modified-Since, If-Unmodified-Since, If-Match, If-None-Match attributes mentioned above).

The header fields are transmitted after the request or response line, which is the first line of a message.

Header fields are colon-separated name-value pairs in clear-text string format, terminated by a carriage return (CR) and line feed (LF) character sequence.The end of the header section is indicated by an empty field(line), resulting in the transmission of two consecutive CR-LF pairs.
