apache的url如何忽略大小写

我使用的是apache+modpython apache的conf文件配置如下 

<VirtualHost 192.168.0.40:80>
 <Location "/AicProject/"> 
  CheckSpelling on
  SetHandler python-program 
  PythonPath "sys.path + ['C:/workspace']" 
  PythonHandler django.core.handlers.modpython 
  SetEnv DJANGO_SETTINGS_MODULE AicProject.settings 
  PythonOption django.root /AicProject
  PythonDebug On 
  Order Deny,Allow
  Deny from all
  Allow from all
  AllowOverride
  RewriteEngine on
  RewriteRule ^(.*)/(.*) [nocase|NC]
  </Location>
</VirtualHost>

试图用 RewriteEngine来忽略大小写 但是没有效果
http://192.168.0.40/AicProject/login可以正常访问

http://192.168.0.40/aicproject/lOgin
http://192.168.0.40/AICPROJECT/logIn
http://192.168.0.40/AICproject/logiN

通过大小写配置 也希望能正常访问 请高手来指点
