我可以使用< img>标签以跨域发送Cookie？ [英] Can I use an <img> tag to send cookies across domains?

问题描述

查看这种情况：

1. www.websitea.com img 标记的 src 属性 www.websiteb.com/image.aspx?id = 5 和 style =display：none


2. www.websiteb .com 除了名称为引荐来源的Cookie和 5 （已验证的查询字符串创建服务器端。）



1. www.websitea.com displays an img tag with a src attribute of www.websiteb.com/image.aspx?id=5 and style="display:none"
2. www.websiteb.com returns an clear image, in addition to a cookie with a name of referrer and value of 5 (created server-side from validated querystring.)

www.websitea.com 或 www.websiteb.com ？

Would the cookie be created on domain www.websitea.com or www.websiteb.com?

确保一系列重定向与querystrings和实现跨域cookie，但我想出了这个形象的想法一点。我想我也可以使用 iframe 。

Currently I'm sure a series of redirects with querystrings and to achieve cross-domain cookies, but I came up with this image idea a little ago. I guess I could also use an iframe.

谢谢！
