摘要： Disclosed is a policy based method for blocking the automatic dereferencing of web beacon links in an e-mail message sent in HTML format with a minimum sacrifice in the HTML body rendering quality. HTML content that potentially contains web beacons is replaced with non-dereferencing elements prior to HTML rendering by the e-mail browser so that the remaining HTML can be rendered as complete as possible without rendering the potential web beacons. Additionally, the present invention also provides a method for removing the HTTP Referer header from referenced external links and activated images. An HTTP redirector service is implemented as a server-based link redirection evaluator application which serves to eliminate the Referer header for the URL requested. Embodiments of the present invention provide for blocking web beacons and removing HTTP Referer headers in both a “down-level” e-mail client and a client which can make programmatic use of an HTML rendering engine.

摘要翻译： 公开了一种基于策略的方法，用于阻止以HTML格式发送的电子邮件消息中的网络信标链路的自动取消引用，并以最小的HTML体素渲染质量牺牲。 可能包含网络信标的HTML内容在电子邮件浏览器HTML呈现之前被非取消引用元素替换，以便剩余的HTML可以尽可能完整，而不会渲染潜在的网络信标。 另外，本发明还提供了一种从引用的外部链接和激活的图像中去除HTTP参考头的方法。 HTTP重定向器服务实现为基于服务器的链接重定向评估程序应用程序，用于消除请求的URL的Referer头。 本发明的实施例提供了阻止网络信标并在“下级”电子邮件客户端和可以使HTML呈现引擎的程序化使用的客户端中移除HTTP引用头。
