ngx_mirror.md

ngx_http_mirror_module 默认开启

• nginx mirror模块: 只能镜像，镜像流量的block不会到真正后端的流量产生影响(可用于测试及灰度, 不能用于waf阻断)
• fasthttp代码修改 /* //For ngx mirror //X-Real-IP x_real_ip := ctx.Request.Header.Peek("X-Real-IP") if len(x_real_ip) > 0 { distCtx.Data["x_real_ip"] = x_real_ip }

//Host host := ctx.Request.Header.Peek("Host") if len(host) > 0 { distCtx.Data["host"] = x_real_ip }

//X-Original-URI request_uri := ctx.Request.Header.Peek("X-Original-URI") if len(request_uri) > 0 { distCtx.Data["request_uri"] = request_uri }
