nginx1.4.7 ip_hash load balancing strategy

[gaoping at richinfo.cn]

hi
     When my nginx is below this structure,Nginx access to the IP proxy server by IP, then nginx ip_hash load balancing, will all requests are routed to the same tomcat, do not know if you have what good method to solve the.
    The ip_hash function can be introduced into a custom IP.      
     Prerequisite: can not change the existing structure, and nginx access to the IP is only aproxy server, and IP client request is not true,
