一个高性能的 WebSocket(s)/HTTP(s)/TCP 中转代理。
关键设计特点：
- 注重稳定性
- 高可用，可以在运行时升级版本，无需担心连接丢失、服务中断、停机
- 在 reload 过程中，会保持转发可以成功。压力测试过程中 reload，测试结果 0 error
- 进程守护，工作进程崩溃自动重启
- 注重性能，在保持跨平台的前提下，会尝试采用性能更高的技术方案
- 减少内存分配来减轻 GC 负担：资源池；LoadOrStore 仅在 Store 时才创建 Value
- 减少内存复制：Reader 使用 Peek 和 Discard 取代 Read
- 避免系统调用：Virtual Listener、Conn 将请求数据转发到进程内 API 服务
- 根据不同的并发场景，使用适当的并发技术
- 注重易用性
- 支持 Web 配置管理
- 零参数配置启动，进入 Web 配置初始化
- 支持加载配置文件目录，可以同时启动多个服务端和客户端
- 客户端支持指向多个服务
- 服务端支持多用户功能
- 客户端自动根据网络状况，智能选择与服务端的通信协议
- 注重隐私保护
- 服务端的端口复用功能，是基于协议目标的特征位置来实现的。例如：应用层 HTTP 协议转发，基于 TCP 数据流，只定位获取第一个数据包的 HTTP 协议头的转发目标，然后将后续数据直接转发
- 不打印敏感信息到日志
- 支持 HTTPS SNI 端到端加密转发

Print version配置文件可以通过 Web 管理后台编辑生成，推荐直接使用 Web 管理后台编辑。
使用默认配置运行，运行后可从日志获取 Web 管理后台地址，用浏览器打开后，进行配置项编辑：
gt server通过指定配置文件运行：
gt server -c ./config.yml使用默认配置运行，运行后可从日志获取 Web 管理后台地址，用浏览器打开后，进行配置项编辑：
gt client通过指定配置文件运行：
gt client -c ./config.yml通过指定配置文件目录批量启动：
