how to redirect domain to sub-domain

[samasamajam]

Hi,
i have 2 registered domains for the website

http://xyz.com

and

http://www.xyz.com

- both URLs can be used to access homepage.
Is it possible to redirect to

http://www.xyz.com

when the user enters

http://xyz.com??

The redirect syntax in apache 1.3 seems to work only with URL-path for the first URL parameter
Do i need to make any modification to the following directive in httpd.conf -
"Redirect permanent

http://xyz.com

http://www.xyz.com

"

Thanks

Use the ServerName directive for xyz.com and the ServerAlias directive for

http://www.xyz.com
