我使用 Apache 2.4 作为反向代理，并根据这帖子中，我不需要 HTTP CONNECT 方法。因此，当我使用以下方法构建 Apache 时，我尝试禁用 proxy_connect 模块配置（静态）选项。
$ ./apachectl -v
Server version: Apache/2.4.29 (Unix)
Server built: Feb 8 2018 12:40:42
$ ./apachectl -M

如您所见，我只启用了：proxy、proxy_http 和 proxy_balancer 模块。
但是，当我运行 nmap 扫描时，它会报告 CONNECT 的 400（错误请求），而我预期的是 405（方法不允许）。
$ nmap -p 443 --script http-methods --script-args 'http-methods.test-all=true,http-methods.retest=1' 10.x.x.xxx

这是我在 apache/conf/extra/httpd-vhosts.conf 开头所写的内容：
<VirtualHost *:443>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} !^(GET|POST|HEAD)
RewriteRule .* - [R=405,L]
以下是 nmap 扫描的 Apache 访问日志：

除了 CONNECT 的 400 状态之外，我对其他一切都很满意。
有什么方法可以让 Apache 返回 CONNECT 的 405 或 501 状态吗？
