這個網站用IE開沒問題
但使用Firefox就會出現這樣子的錯誤訊息

Hey, it worked !
The SSL/TLS-aware Apache webserver was
successfully installed on this website.

If you can see this page, then the people who own this website have just installed the Apache Web server software and the Apache Interface to OpenSSL (mod_ssl) successfully. They now have to add content to this directory and replace this placeholder page, or else point the server at their real content.

ATTENTION!
If you are seeing this page instead of the site you expected, please contact the administrator of the site involved. (Try sending mail to <webmaster@domain>.) Although this site is running the Apache software it almost certainly has no other connection to the Apache Group, so please do not send mail about this site or its contents to the Apache authors. If you do, your message will be ignored.

請問問題是出在哪裡
謝謝

預設首頁檔案附檔名的關係，你若用
http://fish.cs.ntou.edu.tw/index.htm
去看就正常，而會出現你說的那些訊息則是因為讀到
http://fish.cs.ntou.edu.tw/index.html
的關係，雖然只差了一個"l"

但應該是 server 設定首頁檔名順序的關係吧...

不過令我比較奇怪的是
一般server預設都會去找index.html和index.htm
server找不到.html的話
應該會接下來找.htm吧
那麼就是server的問題囉
但是我也架過web server
其順序也都是先找index.html再找index.htm
用Firefox看沒有這種問題
目前還是想不出問題會出在哪
(這部機器不是我的)

我想應該是他的 SERVER 有進行瀏覽器辯視吧, 當不是 IE 的瀏覽器, 就把他導引到 index.html
