Sticky Load Balancing with Varnish - sick backends

[Soesoe]

Hi

oh that was quick - thanks for the fast answers.
right now we can't easly upgrade to a newer varnish version.

the stickyness should only catch if a Session is this (when you logged in)
if you don't have this session cookie no stickyness should be there - for
better performance.
