I have created logout def in python, in that def I am deleting session that I have created after login the user.

I wish to end/del session when the user closes the browser using(X) OR using(alt+4).

how do I call logout url in javascript when user close the browser.

Here is def logout:

@login_required
def logout(request):
    username = request.session['username']
    ip = settings.IP
    headers = settings.HEADERS
    del request.session['username']

Here is urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('logout', views.logout, name="logout"),
]
