Apache 2.4.6 使用基于名称的虚拟主机托管四个域。对 http 端口 80 的调用被重定向到端口 443。每个虚拟服务器都有两个 ServerAlias 参数，用于指令将调用重定向到http://domain-example.com/或者http://www.domain-example.com/到https://domain-example.com/。
问题是http://example2.com/由默认虚拟主机重定向（按顺序排列）https://example1.com/更让人费解的是http://example2.com/somepath正确重定向至https://example2.com/somepath。

有什么想法吗？
谢谢
答案1
这似乎是本地（与服务器无关）Chrome 浏览器 DNS 缓存问题。使用 Safari 和 Firefox 时，所有调用都会产生预期的 URL。只有使用 Chrome 时才会出现上述问题。如果我找到原因，我会进一步更新。

配置虚拟主机时，强烈建议（我强烈建议，如果没有其他人）始终配置一个“默认”虚拟主机，并设置 404 页面或某种重定向到正确的 URL，这样您就不会遇到这种神秘情况。我还会遵循 @TedSpradley 的建议，确保您已清除缓存。我在多个 Web 服务器上都看到过这个问题，浏览器会无限期地缓存页面，从而给您带来意想不到的结果。（虽然不是 DNS 缓存。而是 Web 缓存）
