PING basically tests that the IP protocol is working.  It doesn't help
test the TCP protocol (which runs on top of IP), and it certainly doesn't
test to see if your web server is listening for requests properly.

In order to test this, you need software that uses TCP to make a request
to port 80 on the server.  TELNET can do that.  HTTP does that.  PING does
not.

There might be, that depends on how the web server is configured.  If
there is, HTTPAPI's EXAMPLE7 shows how to send the userid & password.
