Hi,Apologies in advance for a fairly high level question which may not be the norm of this users group.I am trying to understand options and eventually choose a software load balancer for a project I am working on. I am specifically interested in the capabilities of two options - Apache HTTPD mod_proxy_balancer and Varnish (https://www.varnish-cache.org/trac/wiki/LoadBalancing) from the following perspectives:1. Feature set supported like - session stickyness, failover from one node to another in the load balancer farm etc2. Performance/throughput3. Stability of the solution4. Ease of use or time required to setup for typical http(s) load balancing use casesI did try googling for information for a couple of hours but was not successful in finding a good comparison. So I am looking at your experience to get some pointers.Any help would be highly appreciated.Kind RegardsAnurag
