URL Forwarding

[chris at rockfort.com]

I have 2 domain names, siteA.com  and siteB.com
I would to forward siteB.com to SiteA.com so that whenever siteB.com is
requested, it automatically ends up at siteA.
in the zone record for siteB.com I propose to do the following, please tell
me if this is the correct way to accomplish this:


$ORIGIN siteB.com
$TTL 86400
@     IN     SOA    dns1.domain.com.     hostmaster.domain.com. (
                    2001062501 ; serial
                    21600      ; refresh after 6 hours
                    3600       ; retry after 1 hour
                    604800     ; expire after 1 week
                    86400 )    ; minimum TTL of 1 day

      IN     NS     dns1.domain.com.
      IN     NS     dns2.domain.com.


www          IN     CNAME   siteA.com

WOULD there need to be any other directive to add to the above zone file to
accomplish this goal? ot is this altogether incorrect. If so what is the
proper way to do this. Again all I want ot do is to forward www.siteB.com
to www.siteA.com

Thanks

Chris
