Simple web question

By phrreakk ·
Hello, I have a pretty simple web question that I can't seem to find any answers on. I was wondering if anyone had any information or a web site to view that explains the difference between www.yahoo.com and yahoo.com. I know it works for these sites but for some sites these links do not go to the same website. Any help would be greatly appreciated.

I don't know if you are asking about yahoo specifically or just web sites in general that may or may not have the www preceding it. So I will answer it generally. The way the sites work is based on a DNS record and the host header name (the web site name). In the DNS entry they actually have 2 host recorded one titled www and the other blank. Usually they will have the blank host redirect to the www however sometimes they have 2 entries in there web server that looks for both host header names. I hope this is what you were looking for.

If the company does have a DNS host for a blank name then the web site name without the preceding www will not work. I hope this is what you were looking for.
