当我们希望通过 X-redirect 链传播 Etag 作为 Range 请求的 Http 响应（即 Http 206）的一部分时，我们遇到了这种奇怪的行为。似乎 nginx 过滤掉了任何额外的服装标头/tmp 变量，作为通过 x- 的最终响应的一部分重定向非 200 响应。请建议解决此问题。

这是正常与范围请求清除的调试模式下的日志数据，显示自定义标头被过滤掉。

你的两个回答都有

Accept-Ranges: none

表示您的服务器不支持范围请求。

参考：http ://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

  Servers that do not accept any kind of range request for a
  resource MAY send

      Accept-Ranges: none

  to advise the client not to attempt a range request.

不知道你的 nginx 配置。因为只有 http 1.1 支持范围请求，我猜你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），建议使用 1.1 以获得更好的性能。详见参考：http ://wiki.nginx.org/HttpProxyModule#proxy_http_version
