CodeIgniter 路由在 CIFS 挂载上工作，但不适用于本地文件

我们在工作中的开发环境使用一台带有 Apache/PHP 的 centOS 机器，为 CIFS 挂载和本地目录提供不同的虚拟主机。 我们的应用程序是使用 CodeIgniter 2.0 构建

我们最近对路由进行了更改，该更改适用于为装载的驱动器提供服务的虚拟主机，但无法解析本地文件的路由，从而导致 404。

$config['base_url'] = "http://production.host.com"; // the production value of $_SERVER['SERVER_NAME'] essentially

路线：

$route['companyone'] = 'sso/platformsso/requestgenericsso/companyone';
$route['companyone/(:any)'] = 'sso/ptlatformsso/requestgenericsso/companyone/$1';

这适用于以下方案：

<VirtualHost 192.168.1.1:80>
    ServerAdmin me@host.com
    DocumentRoot "/var/mnt/a"
    ServerName "a.tmbc.com"
    ErrorLog logs/a.error.log
    Alias ssaml /var/simplesamlphp/www
</VirtualHost>
<Directory "/var/mnt/a">
    Options  FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>
Directory populated using CIFS mount: mount -t cifs //1.2.3.4/a /var/mnt/a -o rw,username=un,password=pwd,uid=48 --verbose1

但不适用于此方案：

<VirtualHost 192.168.1.1:80>
    ServerAdmin me@host.com
    DocumentRoot "/var/www/html/b"
    ServerName "b.host.com"
    ErrorLog logs/b.error.log
    Alias ssaml /var/simplesamlphp/www
</VirtualHost>
<Directory "/var/www/html/b">
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>
Directory populated using SVN checkout: svn checkout file:///var/svn/repo/trunk /var/www/html/b

.htaccess：

AddType text/x-component .htc
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    # Restrict unused HTTP methods
    RewriteCond %{REQUEST_METHOD} !^(GET|POST|HEAD)
    RewriteRule .* - [R=405,L]
    # Forces SSL
    RewriteCond %{HTTPS} !=on
    RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
    #Removes access to the system folder by users.
    RewriteCond %{REQUEST_URI} ^_sys.*
    RewriteRule ^(.*)$ /index.php/$1 [L]
    RewriteCond %{REQUEST_URI} ^_app.*
    RewriteRule ^(.*)$ /index.php/$1 [L]
    RewriteRule ^(.*).(pdf|exe|doc|mp4)$ /externaldownload/?fileLocation=$1.$2 [R,L]
    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

有什么想法吗？
