I was scratching my head when the three magic meta didn't work in Firefox and Safari.

Apparently it can happen because some browsers will ignore the client side meta, so it should be handled at server side.

I tried all the answers from this post for my class based views (django==1.11.6). But referring to answers from @Lorenzo and @Zags, I decided to write a middleware which I think is a simple one.

So adding to other good answers,

# middleware.py
class DisableBrowserCacheMiddleware(object):

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        response['Pragma'] = 'no-cache'
        response['Cache-Control'] = 'no-cache, no-store, must-revalidate'
        response['Expires'] = '0'
        return response

# settings.py
MIDDLEWARE = [
    'myapp.middleware.DisableBrowserCacheMiddleware',
    ...
