.htaccess htaccess抛出无限重定向

我正在尝试使用htaccess将我的页面重定向到https。同时，我希望其他页面应该在http上工作。下面是我的.htaccess代码

Options +FollowSymlinks
RewriteEngine on
RewriteBase /

# Turn SSL on for index.php
RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{REQUEST_URI} \/trimmApp\/index\.php [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [L]

# Turn SSL off everything exluding index.php (and some files used on index.php that need to serve through https only)

RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{REQUEST_URI} !\/trimmApp\/index\.php [NC]
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [L]

Http到https重定向发生得很好，但是，htpps重定向到另一个，并且这种情况会无限期地发生。我尝试了几乎所有可能的wrt httpd.cong AllowVeride设置

以下是我的重写日志的快照：

不知道一定发生了什么。非常感谢您的帮助。我的linux版本是Centos 5.6
