Is there a more efficient way to use backend webservers with HAproxy+Lua scripts ?

[Burak Çayır]

Hello,

I am a CS student and I am trying to learn HAproxy and Lua API.

I want to load web server pages faster than before. Is it possible with
HAproxy Lua API ? If it is possible , which algorithm I should use ?

my getbackend.cfg
 global

  daemon
  log /dev/log local0
  log /dev/log local1 notice
  maxconn 50000
  lua-load /etc/haproxy/getbackend.lua
defaults
  log               global
  retries                   3
  backlog               10000
  maxconn               10000
  timeout connect          3s
  timeout client          30s
  timeout server          30s
  timeout tunnel        3600s
  timeout http-keep-alive  1s
  timeout http-request    15s
  timeout queue           30s
  timeout tarpit          60s
  option            redispatch
  option            http-server-close
  option            dontlognull

frontend mywebserver
  bind *:8080
  mode http
  use_backend %[lua.choose_backend]

backend backend1
  balance roundrobin
  mode http
  server ws1 192.168.122.232:8080
  server ws3 192.168.122.219:8080

backend backend2
  balance roundrobin
  mode http
  server ws2 192.168.122.72:8080
  server ws4 192.168.122.172:8080

​and my getbackend.lua

​core.register_fetches("choose_backend", function(txn)

if txn.sf:req_fhdr("host") == 'test.com:8080' then
return "backend1"
elseif txn.sf:req_fhdr("host") == 'example.com:8080' then
return "backend2"
end
end)

​King Regards,
