出现.htaccess: Invalid command 'IndexIgnore'错误的解决方法

出现.htaccess: Invalid command 'IndexIgnore'错误
新安装的apache环境，把原有正确的程序放置到环境中出现错误的提示

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, admin@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

在错误日志中查看了一下，看到了两个错误

[Mon May 30 17:32:13 2011] [warn] RewriteCond: NoCase option for non-regex pattern '-f' is not supported and will be ignored.
[Mon May 30 17:32:13 2011] [alert] [client 58.30.224.7] D:/webserver/www/zencart/admin/.htaccess: Invalid command 'IndexIgnore', perhaps misspelled or defined by a module not included in the server configuration

从上面就可以看到问题出现在APACHE的重写规则上
解决办法很简单，把APACHE的配置文件httpd.conf进行修改，开启即可

 LoadModule autoindex_module modules/mod_autoindex.so
