browser-cache - 使用Varnish时浏览器缓存仍然存在

标签 browser-cache varnish varnish-vcl

我认为这似乎与Varnish有关。

注销后，用户状态应更改。但事实并非如此。我已经使用“CTRL + F5”来强制刷新缓存。

所以我有点困惑。我强制刷新浏览器缓存或Varnish缓存。

如果Varnish正在缓存正确的页面(用户未登录)，那么为什么浏览器没有显示它，而是当用户仍在登录时它仍保留在旧页面中。

有什么线索吗？

最佳答案

您的VCL当前正在做的是从请求 header 中删除Cookie并缓存所有请求。这会导致您描述的确切行为。
