Cache-control: pre-check 和 post-check headers 是否仍受 IE 支持?

Are Cache-control: pre-check and post-check headers still supported by IE?

我发现 information Internet Explorer 5 或 IIS 4.0 引入了对 pre-check 和 post-check Cache-control headers 的支持。我找不到太多关于它们是否在更高版本(如 IE 8、9、10 和 11)中仍受支持的信息。

我想在应用程序中删除对它们的支持,但想要不再使用它们的数据。

根据知情人士对your tweet的回复,pre-check和post-checkheaders可能得到支持,但他们的不鼓励使用。

Yeah, short answer is that nobody should use these and all uses of "p*check=0" are junk.

I left p*check support in WinINET in the IE9 rewrite & I doubt removed since, but urge you to not use.
