Linux Apache2 reverseproxy-如何在服务器上设置DocumentRoot？

我已经用apache2配置了reverseproxy。reverseproxy配置如下所示：

<VirtualHost *:80>
    ServerName someserver.com

    ProxyRequests Off

    ProxyPass /             http://123.123.123.123/var/www/someserver.com/htdocs/
    ProxyPassReverse /      http://123.123.123.123/var/www/someserver.com/htdocs/
</VirtualHost>

<VirtualHost *:80>
    ServerName subdomain.someserver.com

    ProxyRequests Off

    ProxyPass /             http://123.123.123.123/var/www/someserver.com/subds/subdomain/
    ProxyPassReverse /      http://123.123.123.123/var/www/someserver.com/subds/subdomain/
</VirtualHost>

ServerName someserver.com
代理请求关闭
ProxyPass/http://123.123.123.123/var/www/someserver.com/htdocs/
ProxyPassReverse/http://123.123.123.123/var/www/someserver.com/htdocs/
ServerName subdomain.someserver.com
代理请求关闭
ProxyPass/http://123.123.123.123/var/www/someserver.com/subds/subdomain/
ProxyPassReverse/http://123.123.123.123/var/www/someserver.com/subds/subdomain/

现在我想为服务器上的两个虚拟主机（123.123.123.123）设置不同的文档根。我试图在服务器上设置虚拟主机，但ServerName目录不起作用

有人知道我如何解决这个问题吗？我肯定有一个简单的解决办法，但我看不出：P 谢谢
