不支持飞牛相册长时间上传大文件

问题表现

• 使用飞牛 ios App 的相册应用里备份视频文件（超过 340MB）时，当上传进度达到 330MB 左右（约耗时 60 多秒）会触发报错，且该问题 100% 必现。

链路环境对比

• 报错链路： 访问域名 (公网) -> Traefik (443) -> 雷池 WAF (80) -> 飞牛 (5666)
• 正常链路： 访问域名 (公网) -> Traefik (443) -> 飞牛 (5666)
  • 注：绕过雷池 WAF 后，大文件上传完全正常。

数据分析与推测

• 上传速度： 约 5MB/s。
• 报错时间点： 文件上传至 330MB 左右报错，换算时间约为 66 秒。
• 推测原因： 该报错点与常见的 60 秒超时限制高度吻合。看起来是雷池 WAF 的后端响应或连接保持超时设置（默认 60s）导致了连接断开。

诉求

• 希望雷池 WAF 能够增加或放开相关超时时间的控制选项（如后端连接超时、读写超时等），以适配大文件长耗时上传的场景
