我想知道是否有人可以建议我做错了什么。
我在前端服务器上设置了 Varnish,这是有效的。我可以把几个公共网站的IP地址(包括CNN)放到这个配置中,它们都被Varnish缓存了。
当我将我的站点 IP 地址之一放入 Varnish 时,我从 Litespeed 服务器收到 404 错误 - 这表明它正在连接到服务器,但显然没有选择正确的站点来显示 Varnish。我在 Litespeed 服务器上有几个域,每个域都有自己的 IP 地址。直接 URL 也是如此。
我猜这是 Litespeed 配置的问题 - 但我们将不胜感激。
作为参考,我正在使用 PageCache 的 VCL 配置文件,它是 Varnish 的 Magento 模块。
