Bug Description

在使用子域名访问网站时，每隔5秒持续请求有时会出现EOF错误：

2025-08-27 11:51:07.231 [W] [httputil/reverseproxy.go:486] do http proxy request [host: test.my.local] error: EOF

之所以要强调5秒，是因为当间隔为1、2、3、4、6、7、8、9、10秒时，都能正确响应，并且100%正确；
但间隔为5秒循环请求时，有大约40%的请求会出现错误。（经测试，极限范围在4.95秒-5.05秒左右）

测试环境中，没有NGINX，没有防火墙，frpc和frps均在同一台机器（经测试不同机器也有这个问题），并且保证被代理的web服务无论怎么请求都是正确返回的。
测试用的frps和frpc均为github release最新版。

尝试调整transport相关的参数但并没有任何影响。

有没有相关的思路，通过配置避免这个问题？5秒整的间隔看起来很有可能是某种内部配置导致的。

frpc Version

v0.64.0

frps Version

v0.64.0

System Architecture

windows/amd64

Configurations

frps.toml

bindPort = 7000
vhostHTTPPort = 8780
subdomainHost = "my.local"

frpc.toml

serverAddr = "127.0.0.1"
serverPort = 7000

[[proxies]]
name = "web"
type = "http"
localPort = 57250
subdomain = "test"

测试脚本

import requests
import time

while True:
    r = requests.post("http://127.0.0.1:8780/hi", headers={
        "Host": "test.my.local"
    })
    print(r.text)
    time.sleep(5)

其中，{"code":200,"msg":"hi","data":null}是正确的结果。

Steps to reproduce

在57250端口准备一个测试用的web服务接口，并且保证请求不会有任何问题
根据配置文件启动frps和frpc
启动测试脚本，每隔5秒带上host请求8780端口
观察日志，可以看到请求有较大概率失败

可能与 https://github.com/golang/go/issues/53472#issuecomment-2852798385 有关。

添加下面这个选项后，可以解决此问题。但感觉不是最优选择……

或者idleCoonTimeout调整到4秒也可以避免这个问题，推测是frpc客户端5秒会主动关闭连接，但frps服务端可能在同时发生请求。最好的办法就是提高frpc客户端主动关闭连接的时间。不太清楚如何配置，调整了几个看似相关的配置项但都没有效果。
