Can I use the director round-robin feature to then check the
req.backend with an if statement in vcl_recv, and issue a 302 (using
the vcl_error 750 hack) to redirect half the traffic to another
server? Is there a better way to do that?
Chris
Hello Chris,
I am not sure I understand what exactly are you trying to accomplish,
but if you only want to have two identical servers behind your Varnish
serving the traffic, that is a very common scenario. You just define a
director with your servers in it and then direct your traffic to this
director. You can choose either the random director, which allows you to
weigh the backends and distribute the load unevenly, or the round-robin
type, which is essentially the same as a random with equal weights.

If your needs are different (you really need to redirect to a different
URL), please clarify.
