A referral is an
ordered list of targets that are tried in turn by a user device. It is designed
for scenarios where the targets are read-only, such as software libraries.
There is no linkage between targets, so using this technique with profiles may
create multiple profiles that cannot be synchronized.
However, it is
possible to define both an ordering method and a target priority for targets in
referrals. Choosing a suitable ordering method appears to result in a
consistent choice of target by all user sessions. But in practice, even when
all of a user's devices are within the same site, intra-site routing problems
can still result in different targets being chosen by different sessions. This
problem can be compounded when devices cache referrals.
Important: This option is not suitable for Profile management deployments
and is generally not supported. However, file replication has been used in some
specialized deployments in which only a single session can be guaranteed and
Active write back is disabled. For information on
