Apache ServerAlias

ServerAlias 這個參數還滿好用的, 之前還傻傻地用了多個 VirtualHost block 來表示.

<VirtualHost *>
    ServerName server.domain.com
    ServerAlias server server2.domain.com server2
    ...
</VirtualHost>

<VirtualHost *:80>
     ServerName pool.ntp.org
     ServerAlias *.pool.ntp.org
     Redirect permanent / http://www.pool.ntp.org/
</VirtualHost>
