Add a custom header on request in a Django middleware

I want to implement a middleware in django, that will append a header on the request's existing headers, before the get_response(request) function.

Though, when trying like this:

request.headers['CUSTOM_HEADER'] = 'CUSTOM_VALUE'

I get an error: 'HttpHeaders' object does not support item assignment
Also in django's request (WSGIRequest), there is no add_headers function like the python's request module.
Any ideas on how this can be accomplished?

Create a simple middleware as below, and put the path in the MIDDLEWARE settings.

from django.utils.deprecation import MiddlewareMixin


class CustomHeaderMiddleware(MiddlewareMixin):
    def process_request(self, request):
        request.META['HTTP_CUSTOM_HEADER'] = "CUSTOM VALUE"
