This is not actually ping, this will send a http request into the server and wait for its response.
This approach will cost more resource and time than ping.

What would you recommend instead?

ping

What about a lightweight solution? It seems oversized to build an app to ping a server.

@rodrigobdz you are assuming web server is running in that host, it might be just ftp,dns,etc. In those cases fetch won't work

@veera83372 Thanks for the heads-up

just a heads up. It doesn't work when you try to ping (fetch) an http URL from a https host.
