Provides CSRF protection & validation.
This middleware adds a CSRF token to a cookie. The cookie value is compared to request data, or the X-CSRF-Token header on each PATCH, POST, PUT, or DELETE request.
If the request data is missing or does not match the cookie data, an InvalidCsrfTokenException will be raised.
This middleware integrates with the FormHelper automatically and when
used together your forms will have CSRF tokens automatically added
when $this->Form->create(...) is used in a view.

cookieName The name of the cookie to send.
expiry A strotime compatible value of how long the CSRF token should last.
