It really depends on what you mean by ''track'' them. Do you
mean track their activities, such as page visits, clicks, etc.? Or
do you simply mean maintaining a Session? If you're talking about
the latter in a clustered enrivonment you can implement sticky
session to keep the user anchored to a single machine. If you want
even more assurance, you can also enable session replication, which
will actually keep the user's session live across your
cluster.How to track users in clustered...
