Varnish and sticky sessions

[Albert Lash]

Use of a cookie would definitely work, and there are probably a bunch of
other simpler methods too. One example - I would add client ip addresses
to the hash and select a backend based upon it, randomizing previously
unknown ip addresses. Depending on where the clients are, the load balance
might become off-balance... my mileage always vary.

I vote for keeping it as a documented configuration rather than a built-in
feature.
