尝试添加像一个条件：

RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTPS}:s on:(s) 

哪些检查，要么HTTPS已关闭或它在，你可以使用反向引用来获取S字符：

Which checks that either HTTPS is off or it's on and you can use a backreference to fetch the "s" character:

RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTPS}:s on:(s) 
RewriteRule ^ http%1://sub.domain.com:2368%{REQUEST_URI} [P,QSA,L]

因此​​，如果HTTPS是关闭的，％1 是空白的，该协议是的http：// 。如果HTTPS上，那么S进行分组和％1 反向引用是一个S，因此协议是 https：//开头。

So if HTTPS is off, %1 is blank and the protocol is http://. If HTTPS is on, then the "s" is grouped and the %1 backreference is an "s", thus the protocol is https://.

然而，这一切假设端口2368可以处理的两个的未加密和SSL / TLS。

However, this is all assuming that port 2368 can handle both unencrypted and SSL/TLS.
