What the heck is CNAME DNS entry into the dns tables?
ie store.yourdomain.com if linked to another site entirely This is done when a person needs a link to another server external from theirs but wants to give the impression that the client has not left the site at all. This requires the dns numbers of the place they are linking to and the information is passed on to tech support so they may add it into the dns tables. This is a little more time to implement as you need the co-operation of two totally different systems administrators to have this implemented.
