Steps to Reproduce
首先，感谢杜文及CFUG各位成员的贡献。
我看这个Bug出现了很长时间，但是都没有得到解决，期望这个问题得到解决。
我查看了已有Issues，也没看到好的解决方案
https://github.com/cfug/dio/issues?q=is%3Aissue%20state%3Aclosed%20HttpException%3A%20Connection%20closed%20before%20full%20header%20was%20received
重现场景：我的应用类似应用宝多任务下载文件，同时执行多个下载任务时，会出现这个报错：HttpException: Connection closed before full header was received，从而导致下载失败。
我这打印出来的报错是这样：DioExceptionType.unknown HttpException: Connection closed before full header was received
Expected Result
正常下载，不会报错导致下载失败
Actual Result
报错：HttpException: Connection closed before full header was received，然后下载失败
