Disable Homepage Cache

[MrCoder]

昨天我们注意到Ruixing的机器上缓存了首页，以至于他获得首页上的CSS并不存在。清空Cloudflare缓存之后，问题消失。

这张卡用于跟踪该问题的解决：

1. 确认Cloudflare是否缓存了首页HTML资源；
2. 理解为何其他人的机器上都没有出现该问题，或者重现该问题；
3. 修改CF的缓存规则（该修改应当计入release日志）

Homepage Response Headers

CF的Response里面有两个有关Cache的Header:

Cache-Control: public, max-age=0, must-revalidate
Cf-Cache-Status: BYPASS

从这两个Header看，CF的缓存规则并没有缓存首页。

• Cache-Control: public, max-age=0, must-revalidate: This header suggests that while the resource is public and can be cached, it should not be stored for any duration (max-age=0) and must be revalidated with the origin server before being served.
• Cf-Cache-Status: BYPASS: This indicates that Cloudflare did not serve this resource from its cache and bypassed the cache for this request.

@danshuitaihejie 请把你请求Homepage时的Response Headers贴到这里。

至少在3个人的机器上发现了这个问题，包括两位设计师和 @iamshaynez 。

后来 @iamshaynez 遇到问题是在发布了一个新版本之后。清空CF缓存之后问题消失。我记得上一次也是清空CF缓存之后问题消失。 所以，最大的概率是CF的问题，其次可能是Docusaurus的问题。

今天发了新版本后我测试了，似乎没有发生，还是很不稳定的样子。也不确定这两天 CF 缓存有没有调整过啥？
