Ghost Proxifier Pro 是一款专为 Windows 平台打造的高性能进程级透明代理引擎，旨在解决现代复杂网络环境下的两大痛点：「特定应用不走系统代理」以及「多重 VPN/代理路由冲突」。 核心亮点描述： 真正的进程级细粒度控制：不同于传统的全局代理或 TUN 模式，它基于 MinHook 直接拦截应用层 Winsock API。这意味着您可以精确指定某个进程（如 Chrome、游戏或特定工具）走代理，而无需修改系统全局路由表。 「全家桶」自动关联技术：Pro 版独有的进程追踪算法。只需接管母进程，它便能智能识别并自动拦截该软件启动的所有关联子进程，彻底告别繁琐的手动配置。 零侵入、高兼容：采用独创的 Lazy Handshake (延迟握手) 机制，完美兼容现代异步 IO
