Flask-SSLify

This is a simple Flask extension that configures your Flask application to redirect all incoming requests to HTTPS.

Redirects only occur when app.debug is False.

Usage

Usage is pretty simple:

from flask import Flask
from flask_sslify import SSLify

app = Flask(__name__)
sslify = SSLify(app)

If you make an HTTP request, it will automatically redirect:

$ curl -I http://secure-samurai.herokuapp.com/
HTTP/1.1 302 FOUND
Content-length: 281
Content-Type: text/html; charset=utf-8
Date: Sun, 29 Apr 2012 21:39:36 GMT
Location: https://secure-samurai.herokuapp.com/
Server: gunicorn/0.14.2
Strict-Transport-Security: max-age=31536000
Connection: keep-alive

HTTP Strict Transport Security

Flask-SSLify also provides your application with an HSTS policy.

By default, HSTS is set for on year (31536000 seconds).

You can change the duration by passing the age parameter:

sslify = SSLify(app, age=300)

If you'd like to include subdomains in your HSTS policy, set the subdomains parameter:

sslify = SSLify(app, subdomains=True)

Install

Installation is simple too:

$ pip install Flask-SSLify
