Apacheの設定がこんな感じ。
#ProxyRequest Off ProxyPass /sticky_plus balancer://sticky_plus ProxyPassReverse /sticky_plus balancer://sticky_plus <Proxy balancer://sticky_plus> BalancerMember http://localhost:3000/sticky_plus loadfactor=10 BalancerMember http://localhost:3001/sticky_plus loadfactor=10 BalancerMember http://localhost:3002/sticky_plus loadfactor=10 BalancerMember http://localhost:3003/sticky_plus loadfactor=10 BalancerMember http://localhost:3004/sticky_plus loadfactor=10 </Proxy>
一応、並列リクエストに強くなったように見える。
