www CNAME record problems

EDIT : Tomcat application issue

Hi,

I have the following problem :

When I type in "www.mydomain.com" OR "mydomain.com" in the address bar, I end up at the same place. However, if I want to go into an application it doesn't react the same.

If I type "http://mydomain.com/appname" it works, but if I type "http://www.mydomain.com/appname" then it displays a message stating that states "Not Found
The requested document was not found on this server. "

I think this has something to do with my DNS settings, but as far as I know it is set up correctly. Any help please!!?

Ok, I have determined that this is not a DNS issue.

If I go to either 'http://mydomain.com/htmlfolder/' or 'http://www.mydomain.com/htmlfolder/' I see the page...

However, when I try to do the same thing to a Tomcat application, I can only access it if I DON'T have 'www' in the URL.

This is very urgent, so if somebody has a clue as to what is going on here...please please let me know...

I don't know whether anybody is interested , but I managed to solve the problem.

I added an <Alias>www.mydomain.com</Alias>
to the host section of the server.xml file in the Tomcat/Conf directory. I restarted Tomcat and voila, it works....

I still want to know why I had to do this in the first place though, so if somebody can point this out to me, I would really appreciate it...
