HEAD method requests the headers that are returned if the specified resource would be requested with an HTTP
GET method. Such a request can be done before deciding to download a large resource to save bandwidth, for example.
A response to a
HEAD method should not have a body. If so, it must be ignored. Even so, entity headers describing the content of the body, like
Content-Length may be included in the response. They don't relate to the body of the
HEAD response, which should be empty, but to the body which a similar request using the
GET method would have returned as a response.
If the result of a
HEAD request shows that a cached resource after a
GET request is now outdated, the cache is invalidated, even if no
GET request has been made.
