htaccess，如果文件夹存在则重定向
问题描述：
如果文件夹安装存在，但我到目前为止还没有运气，我正在尝试重定向用户.
I'm trying to redirect the user if the folder install exists but i had no luck so far.
下面是我的htaccess文件.
Below is my htaccess file.
RewriteEngine On
RewriteBase /enc/project/
# If the setup directory exists in the document root...
RewriteCond %{DOCUMENT_ROOT}/install -d
# ...and you're not in isntall..
RewriteCond %{REQUEST_URI} !(install) [NC]
# ...redirect to setup - with a 302 (temporary redirect) to make sure the browser won't cache the redirect.
RewriteRule ^(.*) /install [L,redirect=302]
# ...rest of htaccess for codeigniter
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
codeigniter项目位于服务器的/enc/project/中，这就是RewriteBase的原因.
The codeigniter project is in the /enc/project/ in my server thats why the RewriteBase.
Project Structure is
htdocs/enc/project/
|-- application/
| |-- project
|
|-- system/
| |-- project
|
|-- install/
| |-- test/
| | |-- test_main.php
| |
| |-- index.php
|
|-- htaccess

尝试这些规则
RewriteEngine On
RewriteBase /enc/project/
# If the setup directory exists in the document root...
RewriteCond %{DOCUMENT_ROOT}/enc/project/install -d
# ...and you're not in isntall..
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# ...redirect to setup - with a 302 (temporary redirect) to make sure the browser won't cache the redirect.
RewriteRule !^install/ install/ [L,NC,R=302]
# ...rest of htaccess for codeigniter
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
