I'm a developer and I'm having trouble setting up some hosting, and I hope you guys can help me out.
I've got a domain I'm setting up for a friend. URLs work fine when I use the short form, like
That is, the pages render properly and I get HTTP/200 responses. When I try
I get a HTTP/502 error. Pinging it gives me "Ping request could not find host www.domainname.com. Please check the name and try again."
I'm stumped, because I don't know enough terminology to formulate a good keyword search. Can anyone give me some info on what I might need to do, to set up some kind of alias so that the standard
www. form will work? I don't know whether to talk to my registrar or my hosting company, what to ask them for, or where to look in the various control panels.
Any help at all -- even just naming the different pieces -- would be helpful. I don't know my TLDs from my domain aliases from my CNAMEs.
