The HTTP method HEAD is used for retrieving headers of the server's response to a request without a response body.
The main difference between the HEAD method and GET is that the HEAD method returns only the response headers, without the actual data body, which helps to reduce the amount of data transmitted and improve transfer performance.
For example, when you browse a list of files on a web server through a browser, it may first make a request using the HEAD method to get only the file information, such as content type, file size, last modified date, etc.
The browser can use this information to display the list of files without actually downloading them, saving time and network bandwidth.
