## Description

An issue was discovered in Django 1.11 before 1.11.22, 2.1 before 2.1.10,
and 2.2 before 2.2.3. An HTTP request is not redirected to HTTPS when the
SECURE\_PROXY\_SSL\_HEADER and SECURE\_SSL\_REDIRECT settings are used, and the
proxy connects to Django via HTTPS. In other words,
django.http.HttpRequest.scheme has incorrect behavior when a client uses
HTTP.
