How does varnish handle request to multiple backend when the vcl "restart" command is run.
Does it use the same backend as the initial request or does it use another backend in accordance to the configured director. i.e. two backends b1 and b2, restart command is in vcl_error request for object from b1 fails, vcl_error runs and the restart command is executed, on the next retry what backend will varnish use, b1 again or what will it act in accordance with the director (if the director was round robin would it use b2)? I know you can explicitly script this in the vcl like in the example provided at http://northernmost.org/blog/some-trickery-or-resilience-with-varnish/ but I currently have our backends using the round robin director and I don't want to explicitly configure specific backends in a preference order.
