发现.htaccess一个很奇妙的问题，

[zhuayi]

http://news.v0913.com
http://news.v0913.com/index.shtml

第一个直接访问到频道目录

第二个却访问到主目录下的shtml。。。

我是用htaccess 绑定的域名

RewriteCond %{HTTP_HOST} ^news.v0913.com$
RewriteCond %{REQUEST_URI} !^/news/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /news/$1
RewriteCond %{HTTP_HOST} ^news.v0913.com$
RewriteRule ^(/)?$ news/index.shtml [L]

apache是

<VirtualHost *:80>
DocumentRoot "e:\v0913.com"
ServerName www.v0913.com
ServerAlias *.v0913.com
<Directory "e:\v0913.com">
allow from all
Options -Indexes
</Directory>
</VirtualHost>

哪位高手能帮我解决下
