我相信有few things of note：
1.一个或多个RewriteCond可以位于RewriteRule指令之前。只有当URI的当前状态与其模式匹配，并且满足这些条件时，才使用以下规则。

1. RewriteRule指令......可以多次出现，每个示例定义一个重写规则。定义这些规则的顺序很重要-这是在运行时应用这些规则的顺序。
   1.在VirtualHost上下文中，模式最初将与URL中位于主机名和端口之后、查询字符串之前的部分（例如“/app1/index.html”）进行匹配。这是（%解码的）URL路径。
   1.如果您希望匹配主机名、端口或查询字符串，请分别使用带有%{HTTP_HOST}、%{SERVER_PORT}或%{QUERY_STRING}变量的RewriteCond。
   你还利用了L| last标志，这使引擎在运行RewriteRule后停止处理更多规则。
   以上几种方式让您了解引擎是如何运行重写的：
   1.按顺序处理RewriteRules（除非您指定L标志，您将对所有规则执行此操作）
   1.每个RewriteRule可以有多个RewriteCond，在考虑RewriteRule之前，所有的RewriteCond都必须匹配。这也意味着RewriteCond必须对每个RewriteRule单独重复（然而，有一个有趣的技术可以将RewriteRules分组到if-then-else块中）
   1.在您的情况下（VirtualHost上下文），默认情况下仅匹配URL路径，除非您手动匹配HTTP_HOST变量。
   考虑到这一点，我发现重写规则存在一些问题（为了可读性，我交换了http和https vhosts，但这并不重要）：

<VirtualHost *:80> <!-- your http:// requests will end up with this block, because 80 is the port for http -->
<IfModule mod_rewrite.c>
    # www to non www for HTTP and HTTPS <!-- I believe HTTPS traffic is NOT handled by this vhost at all, it arrives straight to *:443 queue -->
    RewriteCond %{REQUEST_URI} ^/www\. [NC,OR] <!-- you evaluate path component of your request uri to begin with "www." (i.e. /www.index.html) - this will obviously never match, you however have OR flag, which proceeds to the second condition -->
    RewriteCond %{REQUEST_URI} !^/podcast [NC] <!-- you check if the path does not start with "/podcast" - this is easy to test - try http://www.website.com/podcast and see if you get redirected to HTTPS - I suspect you will not -->
    # Rewrite below works : redirect 80 => https <!-- I suspect it works by accident, please test it out with http://www.website.com/podcast to confirm my theory -->
    RewriteRule ^/(.*) https://website.com/$1 [R=301,L] <!-- we end up here, and regardless of the requested path we issue a 301 redirect to https version of the website. This is marked as Last rule, so the engine should stop processing here -->
    RewriteRule ^/(.*)  http://localhost:9674/++vh++http:%{SERVER_NAME}:80/++/$1 [P,L] <!-- this I believe kicks in when you request a "/podcast" path - this will proxy the request to your http://localhost:9674/ -->
</IfModule>
</VirtualHost>

<VirtualHost *:443><!-- this is where your 301 redirect will com after bouncing through first set of rules above -->
    # REWRITE to get https://www.website.com to https://website.com except for cgi-bin scripts
    RewriteEngine On <!-- this is important, keep it on -->
    RewriteCond %{REQUEST_URI} !^/cgi-bin/search [NC] <!-- you check whether url path does not contain /cgi-bin/search -->
    RewriteCond %{REQUEST_URI} !^/cgi-bin/awstats [NC]<!-- AND does not contain /cgi-bin/awstats-->
    RewriteRule ^/(.*)  https://localhost:8443/++vh++https:%{SERVER_NAME}:443/++/$1 [P,L]<!-- if both conditions above are met - proxy the request to backend and stop further processing. -->
</VirtualHost>

据我所知，没有重写https://www.website.com -> https://website.com的规则，您的https重写检查的唯一位是/cgi-bin
我的建议沿着（这可能不是一个复制和粘贴的解决方案，但希望你已经得到了要点）：

<VirtualHost *:443>    
    RewriteEngine On
    # www to non www for HTTPS
    <!-- checking for the same thing again -->
    RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
    RewriteRule ^/(.*) https://website.com/$1 [R=301,L] <!-- some people might argue second redirect here is excessive since you already arrived at correct host, but I'd leave this for you to sort out -->
    <!-- your /cgi-bin checks can be merged into one regex --> 
    RewriteCond %{REQUEST_URI} !^/cgi-bin/(search|awstats) [NC]
    RewriteRule ^/(.*)  https://localhost:8443/++vh++https:%{SERVER_NAME}:443/++/$1 [P,L]
</VirtualHost>

<VirtualHost *:80>
<IfModule mod_rewrite.c>
    # www to non www for HTTP
    <!-- if you want to keep your `/podcast` on http check it first -->
    RewriteCond %{REQUEST_URI} !^/podcast [NC]
    RewriteRule ^/(.*)  http://localhost:9674/++vh++http:%{SERVER_NAME}:80/++/$1 [P,L]
    <!-- everything else will get redirected to https -->
    RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
    RewriteRule ^/(.*) https://website.com/$1 [R=301,L]
</IfModule>
</VirtualHost>

我也遇到了同样的问题，因为只有一个网站实际上托管在亚马逊lightsail bitnami实现上。
注解掉该行之后

ServerName mywebsite.com:80

在/opt/bitnami/apache 2/conf/httpd.conf文件中，这个问题得到了解决。
