Question

我正在尝试根据传入请求路由流量，而我正在使用的后端服务器是相同的，但端口不同。但是，无论传入请求如何，所有流量都将流向同一个后端pserver。有人可以帮我吗？

frontend defhttps-in

   acl host_portal hdr(host) -i server1:80  
   acl host_mobility hdr(host) -i server1:81  
   acl host_mobility path_beg /HHServlet  
   acl host_mobility path_beg /ota  
   acl host_mobility path_beg /TransportServlet  
   use_backend pservers if host_portal  
   use_backend mobileservers if host_mobility  
   default_backend pservers    


backend pservers  
    balance roundrobin  
    cookie JSESSIONID prefix nocache  
    cookie SERVERID insert indirect nocache  
    option httpchk get /StatusServlet  
    http-check expect ! string red  
    server portal1 server1:80  cookie P1 check  

backend mobileservers  
    balance roundrobin  
    cookie JSESSIONID prefix nocache  
    cookie SERVERID insert indirect nocache  
    option httpchk get /StatusServlet  
    http-check expect ! string red  
    server mobility1 server1:81 cookie M1 check

如何根据传入请求选择haproxy后端（同一服务器使用不同的端口）？
