-# [OPEN] debug-socket-polling-400
-
-## 问题描述
-- 生产环境后台页持续出现 Socket.IO polling 400。
-- 浏览器控制台可见大量：
-  - `GET /socket.io/?EIO=4&transport=polling&sid=... 400`
-  - `POST /socket.io/?EIO=4&transport=polling&sid=... 400`
-- 同时存在无关但可观察现象：
-  - `vue.global.js` 开发版提示
-  - `/favicon.ico` 404
-
-## 已知现象
-- 首次 `polling` 握手能拿到 `sid`，后续带 `sid` 的轮询请求失败。
-- 失败后客户端持续重连，表现为“连接一下又断开”。
-
-## 初始假设
-- 假设 1：反向代理或负载均衡未做会话保持，导致同一个 `sid` 的后续请求落到不同后端实例。
-- 假设 2：CDN/边缘代理对 `/socket.io/` 的长轮询处理不稳定，导致 `sid` 生命周期被中断。
-- 假设 3：客户端当前传输策略触发了不兼容的重连路径，反复创建新 `sid` 又迅速失效。
-- 假设 4：服务端 Engine.IO 对同一会话的请求顺序或超时异常敏感，导致后续 `GET/POST` 被判无效。
-- 假设 5：`vue.global.js` 开发版提示和 `favicon.ico` 404 只是噪音，不是 Socket.IO 400 的主因。
-
-## 当前计划
-- 先继续收集线上现成证据，不改业务逻辑。
-- 对比首次握手与后续 `sid` 请求是否稳定落到同一服务链路。
-- 若证据仍指向服务端/代理层，再决定是否做最小客户端降级或服务端兼容修复。
