did not correct identify HTTP connections when a reverse proxy
connected via HTTPS.
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.");
