Django 1.7 http headers with Apache and WSGI

What I am trying to do:

include HTTP_AUTHORIZATION (or any custom value) in HTTP request header.

Problem:

request.META contain HTTP_AUTHORIZATION when using the development server (python manage.py runserver). But does not exist in request.META when using Apache with wsgi.

Solution:

Although Django official website mention that request headers are included inside request.META. Using Apache with WSGI, request.META will not include all the headers. The solution is to look for HTTP_AUTHORIZATION in request.environ
