我在通过 https 在 IE 上使用 etags 缓存内容时遇到问题。
Chrome 和 Firefox 允许我使用以下组合成功缓存内容
If-Modified-Since
和
If-None-Match
If-None-Match 标头很重要，因为可能以两种不同的方式查看同一页面，这将生成不同的 etag。
这非常有效，除非我在 https 上使用 IE（我尝试过 IE9 和 10）。在这种情况下，它会删除 if-none-match 标头，但不会删除 if-modified-since 标头。这是一个问题，因为现在它为两种不同的查看方式显示相同的缓存内容，因为修改后的时间戳和 url 都匹配。
SSL 证书是有效的，我已经阅读过它可能会导致问题，并且它在 FF 和 Chrome 中都可以使用。有没有办法来解决这个问题？
这是我在 Chrome、IE (http) 和 IE (https) 中的标题。
请注意，IE (https) 中缺少 If-None-Match 标头。如果问题出在服务器响应上，我已经包含了请求和响应。我已经更改了 url 和服务器名称。
