What Is Http Head Used For

The HTTP HEAD method requests the headers that would be returned if the HEAD request’s URL was instead requested with the HTTP GET method. For example, if a URL might produce a large download, a HEAD request could read its Content-Length header to check the filesize without actually downloading the file.

What is the purpose of HTTP head?

The HTTP HEAD request is often used to retrieve meta-information about a resource at a specified URI without transmitting actual data. For example, to check the availability of hypertext links (check for broken links). Requests using the HTTP HEAD method should only retrieve data (server must not change its state).

Which is an appropriate use of an HTTP header?

The HTTP headers are used to pass additional information between the clients and the server through the request and response header. All the headers are case-insensitive, headers fields are separated by colon, key-value pairs in clear-text string format.
