思路：
在html.asp中用<script src="js.asp"></script>方式來顯示內容，在html.asp代碼中，設定一個session，在js.asp進行判斷，如果是設定的值就顯示正常內容，如果不是，就隱藏或顯示其它內容，在js.asp的結尾把session值改變，在html.asp和js.asp中都加一段代碼，使得遊覽器不快取頁面面只能做到簡單的隱藏，使用工具軟體可以看到源檔案，範例程式碼：
html.asp程式碼：
<%
Response.Expires = 0
Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>查看代碼 - www.51windows.Net</title>
<style>
<!--
td { font-family: Tahoma; font-size: 8pt; color: #000080; line-height: 150%;
border: 1 solid #666666; padding: 4 }
-->
</style>
</head>
<body>
<%
session("haiwa") = "hw"
%>
<div align="center">
<center>
<table border="0" cellpadding="0" cellspacing="0" width="480">
<tr>
<td id="tmp"><SCRIPT LANGUAGE="JavaScript" src="js.asp" id="js"></SCRIPT></td>
</tr>
</table>
</center>
</div>
</body>
</html>
js.asp程式碼：
<%
Response.Expires = 0
Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
if session("haiwa") <> "hw" then
response.write "//歡迎查看源檔案"
response.end
end if
%>
//高，這你都能看得出來。我沒有招了。。哈哈
document.write (" 先做後想，先想後做，邊想邊做；只想不做，只做不想，不想不做。------世界是幾乎都被這六種人涵蓋了，如果作為個人能清楚的分析並看出自己屬於哪一類人，至少證明你自己是個聰明人。")
<%
session("haiwa") = ""
