<?php
     *
     * a Pre-Routing Middleware can be; priority < 0:
     *  - LockCheck - check if the client IP is banned > S102|S403
     *  - Auth - if the user is not logged in, but there's a "Remember me" cookie, then logs in > S102
     *
     * Routing Middleware is fixed (RoutingMiddleware::class); priority = 0:
     *  - A middleware that routes the incoming Request and delegates to the matched middleware. > S102|S404|S405
     *    The RouteResult should be attached to the Request.
     *    If the Routing is not defined explicitly in the pipeline, then it will be injected with priority 0.
     *
     * a Post-Routing Middleware can be; priority between 0 and 100:
     *  - Acl - checks if the given route is available for the client. Also checks the auth > S102|S401|S403
     *  - CacheReader - checks if a suitable response body is cached. > S102|S200
     *
     * Dispatcher Middleware is fixed (DispatcherMiddleware::class); priority = 100:
     *  - A middleware which gets the corresponding Action middleware and applies it > S102
     *    If the Dispatcher is not defined explicitly in the pipeline, then it will be injected with priority 100.
     *    The Dispatcher should not set the response Status Code to 200 to let Post-Dispatchers to be called.
     *
     * a Post-Dispatch Middleware can be; priority > 100:
     *  - CacheWriter - writes response body into DataStorage (DB, File etc.) > S102
     *
     * Final Middleware is fixed (FinalMiddleware:class):
     *  - This middleware behaves a bit differently. It cannot be ordered, it's always the last called middleware:
     *    - when the middleware pipeline reached its end (typically when the Status Code is still 102)
     *    - when one item of the middleware pipeline returns with return response (status code is set to 200|40*|500)
     *    - when during the pipeline process an Exception is thrown.
     *
     * When the middleware pipeline is finished the application prints the header and the output.
     *
     * If a middleware other than the Routing, Dispatcher and Final Middleware has no priority set, it will be
     * considered to have priority = 50.
     *
