I'm Juan Manuel and I have a problem with my Login page in Django 1.8.18 (Python 2.7).
When I do "POST" of username/password Form (passes authenticate() and login() well) and have to redirect (HttpResponseRedirect) to my index page, the browser hangs waiting for a response (it stays in the login page).
After POST it wants to redirect to to '/' with a HTTP 302 and stays like that.

[01/Apr/2020 16:19:43] "POST /login/ HTTP/1.1" 302 0

I've noticed a few things:
1) It doesn't happend everytime.
2) On Chrome's developer mode with "Disable cache" mode on works fine.
3) On Firefox works fine.
4) With reverse() it's the same problem (internally calls HttpResponseRedirect()).
5) The problem exists on the Developing Server (Django) and in Production Server (Apache).
When it's hanging like that, if I press F5 (reload), works fine and the redirection goes to the index.
