The HEAD HTTP method is used to gather information and metadata about a specific resource. It's very similar to GET, but instead of retrieving the entire response data, it excludes the body and only returns the headers.
To send HEAD requests with cURL, we can use the -I cURL option:
curl -I https://httpbin.dev/get
The response of the above cURL HEAD request is the following:
HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Alt-Svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000
