How you do HEAD request?

[smoothprogrammer]

I try using HEAD but the response showing that the curl is using GET.

HEAD http://localhost:8080

Sorry for the late reply, I've been busy for a while.

That's correct syntax and I can confirm that working.
Can you check if you get different response when running this command:

curl -sL -v http://localhost:8080 -X HEAD -H "User-Agent: rest.nvim v3.8.4" -w "%{stderr}? time_total:%{time_total}\n? size_download:%{size_download}\n"

This is exact command rest.nvim runs internally when you fire that request.
