            server_name  localhost;
            default_type text/html;
            location = /favicon.ico {
                log_not_found off;
                access_log off;
            }

            set $userName "";
            if ($http_cookie ~* "UserName=(.+?)(?=;|$)") {
                set $userName $1;
            }
　　　　　　　set $realIp $remote_addr;
             if ($http_cookie ~* "ClientRealIp") {
                set $realIp  $cookie_ClientRealIp;
            }
            proxy_set_header X-Real-IP $realIp;

    set $userName $1;
}
