我在 CentOS 7.6 上使用标准 Apache 2.4.6-88 包和 HTTP 安装了 Apache。我尝试在服务器上启用 HTTPS，除了我的 RewriteEngine 规则外，一切正常。我找不到任何关于 RewriteEngine 不支持 mod_ssl 的提及。
我通过安装 mod_ssl 包启用了 HTTPS，Apache 现在从同一设置同时提供 HTTP 和 HTTPS。VirtualHost中有一个声明/etc/httpd/conf.d/ssl.conf，我还没有触及它。我的配置的相关部分如下所示：
# Set up Apache proxying
ProxyRequests Off
ProxyPreserveHost Off
# URLs to handle locally
# Apache built-ins
ProxyPass /icons !
ProxyPassReverse /icons !
# Handle local URLs through Apache
RewriteEngine On
RewriteRule ^/$ /index.cgi [L]
RewriteRule ^/favicon.ico /ssg/favicon.cgi [L,R]
ProxyPass /ssg !
ProxyPassReverse /ssg !
ProxyPass /index.cgi !
ProxyPassReverse /index.cgi !
ProxyPass /robots.txt !
ProxyPassReverse /robots.txt !
# Hand off everything else to the Varnish backend, which will in turn
# forward to the appropriate backend server process.
ProxyPass / http://localhost:6081/ retry=0
ProxyPassReverse / http://localhost:6081/
代理部分工作正常，除“ProxyPass!”规则列出的 URL 之外的所有 URL是交给 Varnish 后端。
但是，重写部分仅适用于 HTTP。因此http://myip/将重定向到和http://myip/index.cgi。在 HTTPS 上，它不起作用，而是代理到 Varnish 后端（它会立即报告错误）。http://myip/favicon.icohttp://myip/ssg/favicon.cgi
我肯定忽略了这里一些显而易见的东西，但我无论如何也想不出是什么。
启用非常详细的日志，它似乎完全忽略了 RewriteRule 部分：

答案1
一位同事终于给我指明了正确的方向。我发现我需要RewriteOptions Inherit在 ssl.conf 文件的 VirtualHost 部分中添加。默认情况下，代理规则是继承的，但重写选项不是。
