Syntax: one or more
alias host and
canonical host pairs
Host Aliases allow you to indicate that one site (the alias host) is a copy of another site (the canonical host), and that the alias host should automatically be translated to the canonical host when indexing.
Any content already indexed on the aliased host will be translated to the canonical host when the next walk is launched.
The hosts are full hostnames, not partial matches. If you want
www.oldhost.com aliased to
docs.oldhost.com aliased to
docs.newhost.com, they needs to be two
separate host alias pairs.
