用我当前的.htaccess，会发生什么情况：

https://www.dukescasino.com/ - 完美运作

https://dukescasino.com/ - 重定向到上面这很棒

下面的两个选项加载正常，但它应该重定向到https版本：

http://www.dukescasino.com/

http://dukescasino.com/

这里是当前的.htaccess：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

我不相信它是相关的，但如果是这样，这里是当前活动插件的列表：

• Advanced Custom Fields
• All In One SEO Pack
• Bop Search Box Item Type For Nav Menus
• Contact Form 7
• Disable Comments
• Google XML Sitemaps
• Jetpack by WordPress.com
• Search & Filter
• Slider WD
• TablePress
• UpdraftPlus - Backup/Restore
• Wordfence Security
• WPide
• WP Smush
• WP Super Cache

执行的测试：

测试A：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

结果： ERR_TOO_MANY_REDIRECTS

测试B：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

结果： ERR_TOO_MANY_REDIRECTS

测试C：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{SERVER_PORT} ^80$
 RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

结果： ERR_TOO_MANY_REDIRECTS

测试D：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

结果： ERR_TOO_MANY_REDIRECTS

测试E：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI}$1 [R=301,L]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI}$1

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

结果： 302找到。此外，尝试使用ErrorDocument处理请求时遇到500内部服务器错误。
