from django.contrib.auth import login
下面是django中的login源代码，请问怎么改才可以在一个浏览器中同时登录多个用户
默认是最新登录的用户的session会覆盖之前用户的session。（就是在django_session表中覆盖，导致之前登录的用户的session被覆盖）
如果是不同的浏览器则不会覆盖，总之同一个浏览器只能同时登录一个用户。
网上有一种方法，是把session改为列表的形式，但是完全没头绪。没办法了，求解，多谢了。

user = request.user
if hasattr(user, 'get_session_auth_hash'):
session_auth_hash = user.get_session_auth_hash()
if SESSION_KEY in request.session:
if _get_user_session_key(request) != user.pk or (
session_auth_hash and
not constant_time_compare(request.session.get(HASH_SESSION_KEY, ''), session_auth_hash)):
request.session.flush()

request.session.cycle_key()

backend = backend or user.backend
