I do not think it is asp.net specific. It is site/server specific and my
bet is that you need to define the host to use in your request.

Just try it with a telnet to website port 80 and type:

GET / HTTP/1.0<enter>
<enter>

Then try again with the hostname you have to use in the URL for this site:

GET / HTTP/1.0<enter>
Host: yourhost.domain<enter>
<enter>

Make sure to send the CR/LF string where I said <enter> and replace
yourhost.domain with the proper hostname.

Please consult your HTTP RFC for more elaborate details.

check_tcp does just that. Do the 3 way handshake to see it is a valid TCP
port and leave.

Protocol knowledge is your friend here.
