google page speed addon告诉我:

The following publicly cacheable, compressible resources should have a "Vary: Accept-Encoding" header:
//some .js and .css files

我不明白这意味着什么.我已经像这样压缩了这些文件:

if (encodings.Contains("gzip") || encodings == "*")
{
    app.Response.Filter = new GZipStream(baseStream, CompressionMode.Compress);
    app.Response.AppendHeader("Content-Encoding", "gzip");
}

这一切似乎都有效.为什么有Vary: Accept-Encoding必要？

我刚刚在Chrome上尝试访问某些页面时发现了一种非常奇怪的行为.它会提示将它们下载为.gz文件而不是加载它们.

这仅适用于当前的Chrome和所有平台.

正确加载页面后,我可以在Inspector上看到这一点

Resource interpreted as Document but transferred with MIME type application/x-gzip:" https://confluence.example.com/display/engp/PR-1221 ".

我知道这些是由配置为使用gzip压缩的nginx服务器提供的,但这没有任何问题.

  gzip  on;  # that's on nginx part

我几乎可以肯定这是nginx配置有问题,但是什么？

是什么让这个问题更加有趣(而且很烦人)是,如果您从超链接复制URL并将其粘贴到浏览器,它将只是正确地打开页面.是的,这只发生在超链接上.

我试图在此找到有关chrome的错误报告,但我唯一能找到的是其他人确实报告了与reddit页面或类似问题相似的问题github.com.
