環境是Apache 2.2.29

網站1對外使用https，主要對外窗口
https://www.aaa.com.tw/index.php
內部IP是 192.168.1.100
網站2對外使用http，是一個簡單的網頁提供資料庫搜尋
http://192.168.0.101/query/index.jsp
內部IP是 192.168.1.101

需要在網站1中的幾個分頁中用iframe嵌入網站2的網頁

以下是網站1的設定檔：
http-vhosts.conf檔

想要讓最後嵌入的網頁變成類似這樣：
https://www.aaa.com.tw/query/index.jsp

目前還在找資料嘗試，想請教各位先進：設定ProxyPass這個方法可行嗎？

如內容或觀念不對，還請各位先進指正。
