Trying to combine byLogWindow and bySession - no luck

Hello,

I try to figure out the best config for our
backhand cluster.

Two things have to be accomplished:
-Good distribution of load
-Session stickyness

So I tried:

byAge
bySession
byRandom
byLogWindow
byBusyChildren

The problem:
If the bySession directive matches, the server list will
contain one entry only. If this one-member list is processed
by byLogWindow, it results in a zero-member list
(seems to be a bug to me) -> user gets an error.

If I try instead:

byAge
byRandom
byLogWindow
byBusyChildren
bySession

there's a good chance not to catch the existing session, as the
hosting machine might have been dropped from the list by
byLogWindow

Any ideas anyone?
