domain CNAME ?

[Chris Cariffe]

how can i take a domain record

mydomain.com.	IN	A	1.2.3.4

and change it to cname to a 

www.mydomain.com.	IN	A	1.2.3.5
mydomain.com.	IN	CNAME	www.mydomain.com.

is it possible?

this is so if a web browser put's in http://mydomain.com/ they get
redirected or a new name of www.mydomain.com

i have a gut feeling that this is going to have to be set up via a http
server redirect but wanted to see if there is a way to CNAME my domain itself

thanks

i did try the above and bind wouldn't start due to errors
