使用重定向匹配 Apache 虚拟主机服务器别名答案

【问题标题】：Apache Virtual Host Server Alias matching using Redirect使用重定向匹配 Apache 虚拟主机服务器别名
【发布时间】：2019-01-27 20:41:39
【问题描述】：

Apache 2.4.6 使用基于名称的虚拟主机托管四个域。对 http 的 80 端口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，用于将调用重定向到 http://domain-example.com/ 或 http://www.domain-example.com/ 到 https://domain-example.com/。

问题是对http://example2.com/ 的调用被默认虚拟主机（按顺序排列的第一）https://example1.com/ 重定向。更让人头疼的是http://example2.com/somepath 正确地重定向到https://example2.com/somepath。

调用和结果摘要：

http://example1.com/    ==> https://example1.com/
http://www.example1.com/    ==> https://example1.com/
https://example1.com/   ==> https://example1.com/
https://www.example1.com/   ==> https://example1.com/

http://example2.com/    ==> https://example1.com/ (<== THIS ONE!)
http://www.example2.com/    ==> https://example2.com/
https://example2.com/   ==> https://example2.com/
https://www.example2.com/   ==> https://example2.com/

http://example3.us/ ==> https://example3.us/
http://www.example3.us/ ==> https://example3.us/
https://example3.us/    ==> https://example3.us/
https://www.example3.us/    ==> https://example3.us/

http://example4.com/    ==> https://example4.com/
http://www.example4.com/    ==> https://example4.com/
https://example4.com/   ==> https://example4.com/
https://www.example4.com/   ==> https://example4.com/

http://example2.com/    ==> https://example1.com/
http://example2.com/somepath    ==> https://example2.com/somepath

VirtualHost configuration:

    *:80                   is a NameVirtualHost
             default server www.example1.com (/etc/httpd/conf.d/virtualhosts.conf:12)

【问题讨论】：

什么是“Serverexample”而不是“ServerName”？混淆不清？除了名称/别名未在其他任何地方显示之外，默认虚拟主机神秘使用的主要原因是默认虚拟主机中省略了 ServerName 并且请求与服务器自己的底层主机名匹配。
好收获。无意的搜索和替换。你是对的。当然不在实际文件中。

【解决方案1】：

这似乎是本地（与服务器无关）Chrome 浏览器 dns 缓存问题。所有调用都会使用 Safari 和 Firefox 生成预期的 url。只有使用 Chrome 才会出现上述问题。如果找到原因我会进一步更新。
