You misunderstand the power of "telnet". If you "telnet somehost" you make a TCP
connection to port 23 on host "somehost". If you "telnet somehost 80" you make a
TCP connection to port 80 on "somehost". This is not different to using a
browser. If "telnet" to port 80 is blocked by the firewall, then the webserver
cannot be accessed by anyone.

If you cannot telnet to port 80 on the web server

a) you are being denied access. The connection will either eventually time out
or die immediately (if they send a TCP reset).

b) the web server is not running (you'll get a "connection refused" message).

So, exactly what happens when you telnet to port 80?

Just in case you are not sure what to do (on a Unix host, you would):

        telnet hostname 80
        <get a connection message>
        GET / HTTP/1.0

After the "GET" you have to hit Enter twice - the first one terminates the HTTP
request. The second terminates the (empty) list of HTTP headers.
