varnish ssl

[me at ibotty.net]

hi,

i don't know whether i completely understand what you are trying to do.

i understood, that your load balancer understands https traffic and
passes cleartext traffic to the webservers. if that is right, instead of
your proposed stack

> Public => varnish(x2) => loadbalancer => Web servers (x4)

you might do the stack (your notation)

public => loadbalancer => varnish(x2) => web servers (x4)

the load balancer won't do as much work, because varnish will load
distribute as well. that might or might not work in your case (i'm
pretty confident it in fact will work).

good luck,
