## 404 頁面，卻回傳 Http Status 200 的解法
https://www.sitepoint.com/community/t/iis-custom-404-page-gives-200-response-code/25313

這樣 404 頁會回傳 Status 200 ，不合需求

<customErrors mode="On" redirectMode="ResponseRewrite">
	<error statusCode="404" redirect="404.aspx"/>
</customErrors>

解

<% Response.Status = "404 Not Found" %>
