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 resulted in 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. HttpRequest.scheme now respects SECURE_PROXY_SSL_HEADER, if it is configured, and the appropriate header is set on the request, for both HTTP and HTTPS requests. If you deploy Django behind a reverse-proxy that forwards HTTP requests, and that connects to Django via HTTPS, be sure to verify that your application correctly handles code paths relying on scheme, is_secure(), build_absolute_uri(), and SECURE_SSL_REDIRECT. For Debian 8 "Jessie", this issue has been fixed in python-django version 1.7.11-1+deb8u6. We recommend that you upgrade your python-django packages.
