Nginx：对于Http范围请求ie 206，在x重定向链的情况下，会阻止自定义头

当我们希望将Etag作为范围请求（即Http 206）的Http响应的一部分通过X重定向链传播时，我们遇到了这种奇怪的行为。对于非200响应，nginx似乎通过X重定向过滤掉了作为最终响应的一部分的任何附加Costude headers/tmp变量。 请建议解决此问题

下面是调试模式下的日志数据，用于正常vs范围请求清除，显示正在筛选的自定义头

你的两个回答都是正确的

Accept-Ranges: none

表示您的服务器不支持范围请求

参考：

不知道你的nginx配置。因为只有http 1.1支持范围请求，我猜您可能错过了这个指令：

 proxy_http_version 1.1;

Nginx代理模块默认使用http 1.0。但是，如果您的上游服务器支持http 1.1（应该支持），建议使用1.1以获得更好的性能。

我在aria2c中遇到了无效范围标头错误，这对我很有帮助，谢谢
