nginx - 使用gzip时缺少etag [英] nginx - missing etag when gzip is used
问题描述
如果我设置nginx使用gzip，它会删除任何etag标题。
If I setup nginx to use gzip, it removes any etag header.
这背后的原因是相同的资源不能是逐字节相同的给定gzip有各种压缩级别。
The reasoning behind this is that the same resource cannot be byte-for-byte identical given that gzip has various compression levels.
但是nginx也删除了一个弱etag，这意味着资源在语义上是等价的。这似乎是nginx的错误行为。
But nginx also removes a weak etag, which just means that the resources are semantically equivalent. This seems like incorrect behavior by nginx.
我错过了什么吗？如果没有，有没有办法解决这个问题？
Am I missing something? If not, is there a way to fix this?
