Currently I am experimenting with curl flags, looking how to get only the response headers, follow the redirection if any, encryption and authentication used and the round trip time.
What flag should I use to hide/disable the HTML body in the output?
https curl

How to make curl disable html output
Use the -s flag (for silent operation) and redirect stout (>) to (eg) /dev/null (or, if you're on Windows, simply NUL)
This, inc combination with -D <file> (aka --dump-header) may give you the output you are looking for.
The curl manpage has more information on the command-line options which may be helpful.
Example
$ curl -s https://superuser.com -D su.txt > /dev/null
$ less -FX su.txt

What about a Windows environment that uses git bash to curl ?
– user876358
Feb 25 at 17:42
Windows' equivalent to/dev/nullis simplyNUL; I assume git bash will respect that but cannot test at the minute. I have updated my answer to include that.

In addition, some quick searches indicates that git bash implements /dev/null, so/dev/nullmay work in that case!

You can discard the body while still keeping the headers by telling curl to dump them on stdout:
$ curl -D/dev/stdout -o/dev/null -s https://superuser.com
HTTP/1.1 200 OK
Cache-Control: private
Content-Type: text/html; charset=utf-8
X-Frame-Options: SAMEORIGIN
X-Request-Guid: a599d44b-705c-4615-a8d8-80c7614bd64f
...
-D/dev/stdout: dump the headers on standard output
-o/dev/null: discard the body
-s: disable the progress meter
