Well, all URLs start with "http://", that indicates the protocol. if
you don't type it in, the browser will add it.
WWW is just a convention to indicate the World Wide Web, it's not
binding. A server can be www.something.com, www2.something.com,
wwwwww.something.com, etc.
A lot of sites just alias "www." to their main address, like my
site. You can reach it as http://www.blj8.com or http://blj8.com because
www.blj8.com is just an alias to blj8.com.
WWW can be on any port, really... Port 80 is the standard, but I have
seen web sites all over the port range, both with and without the
"www" part. The only thing resembling a restriction on that is that on
Unix, only the superuser or the system can use a port# below 1024, so if
you see a site on, say, port 8080, it's likely that that's a user
running their own site with their own server.
Hope that helps,
