Actually there's another way too (I was probably still sleeping while
writing the email this morning...). You can use check_tcp with send and
expect strings to test it.

Just use telnet and send something like this (two CRs after the "Host:"
line; change the hostname to the one associated to your server.):

- --
GET / HTTP/1.1
Host: www.example.com

- --

Look at the reply, then use this send string in check_tcp:
"GET / HTTP/1.1\r\nHost: www.example.com\r\n\r\n"

And the expect string should match whatever you got in reply in telnet
(I guess something like "HTTP/1.1 401 Authorization Required").
