Apache代理错误重定向

Question

我有以下Apache httpd代理：

<VirtualHost *:80>   
    DocumentRoot "/dados/www/_sistemas"
    ServerName mydomain
    <Directory "/dados/www/_sistemas">
        Options Indexes FollowSymLinks 
        AllowOverride all
        Order Deny,Allow
        Allow from all
    </Directory>

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass /reunioes http://anotherhttpdserver/sistemas/reunioes/web
    ProxyPassReverse /reunioes http://anotherhttpdserver/sistemas/reunioes/web

</VirtualHost>

当我尝试http://mydomain/reunioes时，它会重定向到http://mydomain/sistemas/reunioes/web

如何解决这个问题？
