Take the 2-minute tour ×  I'm a bit confused as the following
points:    1. There is a simple text website, with no
javascript, that works only with the prefix.
http://www.mysite.corporation.com works but
http//mysite.corporation.com will not work. What could be going
on?   2. I run a few LAMP vps' and don't recall ever having
trouble with the leading www   3. Why do people write URLs with
a www. Is there some history behind this? share|improve this

www is just a subdomain. The reason the specific site doesn't
work without the www subdomain can either be a misconfigured DNS
or a misconfigured configuration.  You can try to do a nslookup
to find out to which IP's they are assigned (to check the DNS
settings are correct):  Example of my own domain:  nslookup
responsible-disclosure.com Server:  router.home  Niet-bindend

responsible-disclosure.com  nslookup www.responsible-
