界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

HTML5: Overly Permissive Referrer-Policy

Java/JSP
Universal

Abstract

将 Referrer-Policy 标头设置为 Unsafe-URL 可能会导致应用程序向第三方站点暴露敏感站点和用户数据（包括会话标记、用户名和密码）。

Explanation

默认情况下，浏览器不会将包含来自 HTTPS 之请求的引用标头发送到未加密的 HTTP 链接。然而，请求目标若也为 HTTPS，无论来源如何，都将发送标头。开发人员可能会将敏感信息留在 URL 中，这些敏感信息会通过引用标头向第三方站点暴露。Referrer-Policy 标头会被引入，以控制与引用标头相关的浏览器行为。Unsafe-URL 选项会删除所有限制，并随每一个请求发送引用标头。

示例 1：以下代码配置了受 Spring Security 保护的应用程序，以禁用默认的安全引用策略：


	<http auto-config="true">
        ...
        <headers>
            ...
            <referrer-policy policy="unsafe-url"/>
        </headers>
	</http>
