Hi, There's no stickyness involved with the round-robin director. But from what you are describing, Varnish is doing what you ask it to do: it caches from one backend and keep serving the cached content (ie. it doesn't need to go to the backends anymore).
If you wish to have a non-caching loadbalancer, then then "return (pass);" at the end of vcl_recv and you'll be ok. Otherwise, what behavior do you wish to obtain? -- Guillaume Quintard On Wed, Nov 23, 2016 at 3:59 PM, Sreenath Kodedala <[email protected]> wrote: > http://stackoverflow.com/questions/40751646/varnish-4- > to-cache-from-multiple-servers-with-different-content > > > Using varnish 4 to cache different content of same request from multiple > servers.
