我做了两件事，现在似乎消失了。

I did two things, and the issue seems to disappear for now.

1. 更新我的chrome / firefox



2. 将其添加到settings.py

1. Update my chrome/firefox

2. Add this into the settings.py

SESSION_COOKIE_AGE = 1209600＃2周内过期

SESSION_COOKIE_AGE = 1209600 #expire in 2 weeks

然而，第二个是自动由Django从文档配置。可能我的一些使用Cookie的javascripts会影响到期时间

However, the 2nd one is automatically configured by Django from the docs. Probably some of my javascripts playing with cookies affect the expiration time
