Varnish already support load balancing HTTP 1.1 and Web Socket requests, e.g. https://www.varnish-cache.org/trac/wiki/LoadBalancing
Since we already using
Varnish for caching purpose, are there any benefit if we add
ha proxy in front of
Varnish for load balancing, or should we just use Varnish for load balancing?
Seems this approach is quite rare, and why?
