The HEAD method in the HTTP protocol is a request made by a client to a server for a URL’s header information. The server responds with the header information such as the Content-Type, Last-Modified, Expires, Content-Length, and other metadata about the requested resource. Unlike the GET method, the server doesn’t send the actual content of the page or file requested. This method is typically used to check if a resource has changed before requesting its actual contents. The HTTP HEAD request is a very useful tool to improve performance, reduce network load, and optimize the client’s experience.
