In descending order of personal preference:

#1: use curl

$ curl -I [URL you're testing]

or

$ curl -s [URL you're testing] &> /dev/null

and check the return code.

I prefer curl because it does SSL and gives you the most diagnostic
information about what's going wrong with the server: the hostname
doesn't exist, nothing's listening on port 80, SSL/TLS is screwed up,
it took too long to connect, etc.

#2: use netcat

$ echo -e 'GET / HTTP/1.0\r\n\r\n' | nc [webserver's hostname] 80

#3: if you really, really, really have to do it with nothing but bash,
you can create a named redirect to a tcp port:

$ exec 5<>/dev/tcp/[hostname]/80
$ echo -e 'GET / HTTP/1.0\r\n\r\n' >&5
$ cat <&5
