如何在apache反向代理服务器上强制将http重定向到https？

我有一个带有http和https服务的apache反向代理服务器。我想强制将http重定向到https。我应该如何配置配置文件？

推荐而且更安全的方法是使用VirtualHost：

<VirtualHost *:80>
   ServerName www.example.com
   Redirect permanent / https://www.example.com/
</VirtualHost>

正如我所说，Apache建议使用VirtualHost配置

举例如下：

谢谢，它可以工作，我使用ProxyPass原版，但不起作用。

<VirtualHost *:80>
   ServerName www.example.com
   Redirect permanent /login https://www.example.com/login
</VirtualHost>

RewriteEngine On
# This will enable the Rewrite capabilities

RewriteCond %{HTTPS} !=on
# This checks to make sure the connection is not already HTTPS

RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
# This rule will redirect users from their original location, to the same location but using HTTPS.
# i.e.  http://www.example.com/foo/ to https://www.example.com/foo/
# The leading slash is made optional so that this will work either in httpd.conf
# or .htaccess context
