Is it possible to set a cookie for http://www.example.com from a PHP file located at https://secure.example.com? I have some code that was given to me, that appears to try and fails at this. I was wondering if this is possible at all.

推荐答案

网页只能为第二（或更高级）级域设置Cookie

Webpages can only set cookies for the second (or higher) level domain that they belong to.

这意味着 secure.example.com 可以读取和设置 secure.example.com 或 .example.com ，后者也可以通过 www.example.com

This means that secure.example.com can read and set cookies for secure.example.com or .example.com, the latter of which can also be read and set by www.example.com

最后一个注意事项：如果安全标记设置在Cookie上，则只能通过https连接。

One last note: If the secure flag is set on a cookie, it can only be read and set over an https connection.
