django 不同选项卡上的不同会话（未知数量的不同会话）

Question

我正在尝试创建一个 Django 应用程序，其中同一用户可以在同一浏览器上打开两个选项卡并作为两个不同的会话登录，最好仍然使用 cookie。

一些背景：我的应用程序是为其他网站提供的服务，用户可以从客户网站转到我的网站。所以用户进入我的域，但由于他们来自不同的站点，因此他们的帐户不能混用。

注意：如果有帮助，我可以将用户重定向到每个客户端站点的唯一 URL。

我该如何解决这个问题？有现成的解决方案吗？

谢谢！

我最终使用了评论中链接的 this question that AdolAurion 中的解决方案。注意：我的会话与那里的解决方案有点不同：
