rewrite rule leads to infinite rewrite loop at apache

[javalishixml <javalishixml@xxxxxxx>]

Hi Gurus,

Just a silly question this is. But I really suffer it too much ...   :(

I'm using rewrite module to do rewrite url. I made below rule:

RewriteCond %{SERVER_PORT} !^443$

RewriteCond %{HTTP_HOST}   ^www.jco.com.cn$

RewriteCond %{REQUEST_URI} ^/myjco/mySecurity

RewriteRule (.*) https://www.jco.com.cn/myjco/mySecurity [L,R]

It works fine.  Any access to http://www.jco.com.cn/myjco/mySecurity will rewrite to https://www.jco.com.cn/myjco/mySecurity

But if I make below rule:

RewriteCond %{SERVER_PORT} !^443$

RewriteCond %{HTTP_HOST}   ^rm.jco.com.cn$

RewriteCond %{REQUEST_URI} ^/myjco/orders

RewriteRule (.*) https://rm.jco.com.cn/myjco/orders [L,R]

The browser returns error showing the apache is in an infinite rewrite loop. 

I turned on the rewrite module's log to 3 and I got below information:
