I just realized today that 2.0.2 has been released. I installed 2.0.2
and it fixed the problem ( I was testing with 2.0.1 and 2.0 beta
before). With 2.0.2 round robin now chooses different hosts as
expected. I must have checked for the latest version just before the
page was updated. I should have included the version info in my
Is it possible that the fix to the random director in this release
fixed round-robin as well?
In addition I will note that round-robin load balance selects
different hosts on our top page as desired. After a session cookie is
issued it stuck with one host (sticky session) which is what we want.
I could not find any varnish docs on this and was concerned sticky
session was not implemented. I even found some posts on this list
suggesting that it was not there and would need to be implemented in
the vcl. However it appears to work fine out of the box. Can you (or
anyone) confirm that sticky session is implemented?

Great tip! Thanks.
