WAF 如何将域名负载到ip+路径

比如域名 baidu.com 上游服务器地址 http://172.18.39.164:4000/main/xx/42766

但是雷池配置完，还是指向了 根路径 http://172.18.39.164:4000，导致子路径{/main/xx/42766}没有转入

使用 nginx是可以的，类似配置如下

1server
2{
3    listen 9017;
4    server_name 18.167.109.xxx;
5    location / {
6      proxy_pass http://172.18.39.164:4000/main/xx/42766;
7      proxy_http_version 1.1;
8      proxy_set_header Upgrade $http_upgrade;
9      proxy_set_header Connection "Upgrade";
10      proxy_set_header Host $host;
11      proxy_set_header X-Real-IP $remote_addr;
12      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
13      proxy_set_header X-Forwarded-Proto $scheme;
14    }

不支持
