从 1.13.4 版本起新增了 mirror 模块的支持，官方关于 mirror 模块的介绍：

QuoteThe ngx_http_mirror_module module (1.13.4) implements mirroring of an original request by creating background mirror subrequests. Responses to mirror subrequests are ignored.

即在某个路径时，同时向后端发送一个镜像请求，但是会忽略镜像请求的响应结果。
示例配置如：

Quotelocation / {
mirror /mirror;
proxy_pass http://backend;
}

location /mirror {
internal;
proxy_pass http://test_backend$request_uri;
}
