Doc Text:
An HTTP detection flaw was discovered in Django. If deployed behind a reverse-proxy connecting to Django via HTTPS, django.http.HttpRequest.scheme() incorrectly detected client requests made using HTTP as using HTTPS. This resulted in incorrect results for is_secure() and build_absolute_uri(), and HTTP requests were not correctly redirected to HTTPS in accordance with SECURE_SSL_REDIRECT.

Description msiddiqu 2019-06-27 08:24:15 UTC 
When deployed behind a reverse-proxy connecting to Django via HTTPS, ``django.http.HttpRequest.scheme`` would incorrectly detect client requests made via HTTP as using HTTPS. This entails incorrect results for ``is_secure()``, and ``build_absolute_uri()``, and that HTTP requests would not be redirected to HTTPS in accordance with ``SECURE_SSL_REDIRECT``.
