Overview

This middleware provides Cross-Site Request Forgery protection.

It securely generates a masked (unique-per-request) token that can be embedded in the HTTP response (e.g. form field or HTTP header). The original (unmasked) token is stored in the session, which is inaccessible by an attacker (provided you are using HTTPS). Subsequent requests are expected to include this token, which is compared against the session token. Requests that do not provide a matching token are served with a HTTP 403 'Forbidden' error response.
