ExpressiveRedirectHandler is a package that contains Mezzio middleware for handling redirect that fit with mezzio-skeleton for following conditions:

1. When the given url to RedirectResponse is not registered in routing config

For example, we use RedirectResponse instance in our Middleware:

use Laminas\Diactoros\Response\RedirectResponse;
// ...
$redirect = '/foo'; // may be a variable from GET
return new RedirectResponse($redirect);

if the passed $redirect as url is a valid and registered in the routes, it uses default RedirectResponse implementation, otherwise, it will redirect to default default_url registered in config/autoload/expressive-redirect-handler.local.php:

For example, we define:

<?php

return [

    'expressive-redirect-handler' => [
        'allow_not_routed_url' => false,
        'default_url' => '/',

        'options' => [
            'exclude_urls' => [
                // 'https://www.github.com/samsonasik/ExpressiveRedirectHandler',
            ], // to allow excluded urls to always be redirected
            'exclude_hosts' => [
                // 'www.github.com'
            ],
        ],
    ],

    // ...
];

It means, we can't allow to make redirect to outside registered routes, whenever found un-registered url in routes, then we will be redirected to default_url. It also disable redirect to self, so you can't redirect to self.

For specific urls that exceptional ( allowed to be redirected even not registered in routes), you can register at exclude_urls/exclude_hosts options.

if you define exclude_urls/exclude_hosts options, which one of them is your own current url/host/domain, its your risk to still get "infinite" redirection loops. so, make sure exclude_urls/exclude_hosts is not your current own.

1. When you want to redirect to specific url based on header status code

<?php
return [

    'expressive-redirect-handler' => [
        'allow_not_routed_url' => false,
        'default_url' => '/',
        'header_handler' => [
            'enable' => true, // enable it!
            'headers' => [
                401 => '/login',
                503 => '/maintenance',
            ],
        ],
    ],
    // ...
];

Based on the configuration above, when header status code is 401 or 503, it will be redirected to its paired value.
