我需要在同一台主機下同時使用http和https的功能，然而在啟動apache的時候出現問題，訊息如下
[Fri Feb 24 12:36:17 2012] [warn] _default_ VirtualHost overlap on port 80, the first has precedence [Fri Feb 24 12:36:17 2012] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
解決方式
NameVirtualHost *:80 NameVirtualHost *:443
