To view the HTTP headers of any URL all you need to do is run the following with cURL:

$ curl -I

The response should look something like this:

HTTP/2 200
accept-ranges: bytes
cache-control: max-age=604800
x-cache: HIT
content-length: 1270

If your URL has query strings then you will need to add double quotes:

curl -I ""
