Http Pipelining Config (HA Proxy + Spray)

@sattiwari wrote:

In our existing system, haproxy is used for load balancing requests from clients (spray based) to server (spray-can based). Config is following:

API Client
host-connector {
max-connections = 100
max-retries = 0
max-redirects = 0
pipelining = on
}

HA Proxy
defaults
mode http
option http-server-close
option forwardfor except 127.0.0.0/8
option redispatch
retries 3
timeout http-request 10s
timeout queue 1m
timeout connect 10s
timeout client 1m
timeout server 1m
timeout http-keep-alive 10s
timeout check 10s
maxconn 3000

API Server
server{
server-header=""
pipelining-limit=0
}

I am getting premature connection closed in this setting. I think this is coming because on the same connection HA Proxy sends more requests and my spray server has pipelining-limit 0.

Should i remove http-server-close from ha proxy because i dont want http-close on server side (This will put HA Proxy in tunneling mode where i dont see any disadvantage). Also, I will add increase pipelining-limit to 1024 in spray server.
