.htaccess 重定向到https几乎可以正常工作，但不是很正常

我有一个网站，我想有以下重定向：

1. http://mysite.net     => https://www.mysite.com
2. http://www.mysite.net => https://www.mysite.com
3. http://mysite.com     => https://www.mysite.com
4. http://www.mysite.com => https://www.mysite.com

我已经取得了1、2和3的成绩，但我在第四个方面遇到了麻烦，因为“重定向太多”。这是我的htaccess：

RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.com$ [OR]
RewriteCond %{HTTP_HOST} ^(www.)?mysite\.net$
RewriteRule ^/?$ "https\:\/\/www\.mysite\.com\/" [R=301,L]

# Use PHP5.3 as default
AddHandler application/x-httpd-php53 .php

# Send all traffic of main domain to subdirectory

RewriteCond %{HTTP_HOST} ^(www.)?mysite.com$
RewriteCond %{REQUEST_URI} !^/sites/mysite.com/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ sites/mysite.com/$1 [L]

RewriteCond %{HTTP_HOST} ^(www.)?mysite.com$
RewriteRule ^(/)?$ sites/mysite.com/index.php [L]

---

有什么帮助吗？

蚂蚁神奇的解决方案是：

RewriteEngine on

RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{HTTP_HOST} ^(www.)?mysite\.com$ [OR]
RewriteCond %{HTTP_HOST} ^(www.)?mysite\.net$
RewriteRule ^/?$ "https\:\/\/www\.mysite\.com\/" [R=301,L]

# Use PHP5.3 as default
AddHandler application/x-httpd-php53 .php

# Send all traffic of main domain to subdirectory

RewriteCond %{HTTP_HOST} ^(www.)?mysite.com$
RewriteCond %{REQUEST_URI} !^/sites/mysite.com/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ sites/mysite.com/$1 [L]

RewriteCond %{HTTP_HOST} ^(www.)?mysite.com$
RewriteRule ^(/)?$ sites/mysite.com/index.php [L]
