HTTP Request Methods: HEAD
HEAD method is identical to the
GET method except that it only returns the HTTP headers and not the actual payload (without the response body). This is useful for getting the metadata written in response headers, without having to send the entire content. This winds up saving time and bandwidth. Web browsers usually don't send
HEAD requests. This method is sometimes used by search engine bots and other automated tools to probe for the existence of a file or to check its last modification time.
