需求：
想要讓使用者無論輸入 http://192.168.1.2/Web 或是 http://192.168.1.2/Web/ 時，都會自動連到 http://192.168.1.2/Web/index.html
問題：
但依目前這個設定值，最後網址都會變成 http://192.168.1.2/Web/index.html/index.html/index.html/index.html/index.html/index.html/index.html/index.html/index.html/index.html/index.html/index.html/ 這種網址，造成網頁找不到，還請各位大神協助指點迷津，謝謝。
