我需要将（透明）http://test.mywebsite.com重定向到http://mywebsite.com/test
在Apache2中，我通过在VirtualHost部分添加 ServerAlias * .mywebsite.com 来编辑mywebsite.com.conf文件。然后，我在webmin中重新启动了Apache服务。
最后，我创建了一个新的.htaccess规则：
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.mywebsite.com$ [NC]
RewriteCond %{HTTP_HOST} ^test\.mywebsite\.com [NC]
RewriteRule (.*) http://www.mywebsite.com/test/$1 [L,R=301]
但是，我发现了 Page not found 错误，现在我不知道该怎么办......
有什么建议吗？感谢。

这是完整的.htaccess文件：
SetEnv REGISTER_GLOBALS 0
# MASK FILES IN DIRECTORIES
Options -Indexes
Options -MultiViews
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mywebsite\.com$ [NC]
RewriteRule ^(.*) http://www.mywebsite.com/$1 [QSA,R=301,L]
RewriteCond %{HTTP_HOST} !^www.mywebsite.com$ [NC]
RewriteCond %{HTTP_HOST} ^test\.mywebsite\.com [NC]
RewriteRule (.*) http://www.mywebsite.com/test/$1 [L,R=301]

我想简化我的问题，所以这是一个新的挑战。这样我们就不再关心文件夹重定向，而只关心变量作为子域。因此，我尝试编写另一条规则，将http://test.mywebsite.com重定向到http://mywebsite.com?sub=test。这是我的（非工作规则）：
RewriteCond %{HTTP_HOST} ^test\.mywebsite\.com [NC]
RewriteRule (.*) http://mywebsite.com/index.php?sub=$1 [L,R=301]
此规则将 test.mywebsite.com 重定向到 mywebsite.com/index.php?sub =
