problem with CNAME record

[Ken Lyons - Graphix Wizard/Data-Forms]

RE: ok thanks, I thought maybe I don't need an http-server for url 
forwarding.

DNS is just a phonebook: Name to a number (A record),   Name to a Name 
(CNAME) and Number to a Name (PTR).
URLs are all part of the HTTP system thus require a server.
Based on request,  you could do    *.domain.com  cname example.com. in 
dns..so   example.com server would get the requests.

The server would need to be setup with virtual hosting..since the 
request would still appear to before  *.domain.com.
I would normally setup a index.cgi script to redirect to where you want 
the user to go to, or use extra features proveded by the HTTP Server tp 
same end.
