Static cache redirection

[artisanbarista]

Bug description

Static cache is set while redirecting.

How to reproduce

Lets say i have 2 pages with STATAMIC_STATIC_CACHING_STRATEGY=half

https://www.test.com/party https://www.test.com/eu/party

I have a middleware that in case u visit https://www.test.com/party from a european ip it will redirect to https://www.test.com/eu/party

return redirect('/eu/party', 302, [
    'X-Redirected-By' => 'Party Redirecion',
    'X-Redirected-From' => '/party',
]);

Once this redirection is executed and user lands https://www.test.com/eu/party there is a button in that page to say this is not available for european users and if you landed here by mistake to click on a button to go to https://www.test.com/party?mistake=true

Unfortunattely this does not work correctly because statamic static cache allready cached https://www.test.com/eu/party while redirecting and when the user clicks on the button to go to https://www.test.com/party?mistake=true it continue showing https://www.test.com/eu/party static cached page.

As a fix for this problem I have added this

if ($event->response->getStatusCode() === 302) {
    return;
}

https://github.com/statamic/cms/blob/3956ab1343eef8b20d89c5281160c05c63f279c0/src/StaticCaching/Cachers/ApplicationCacher.php#L51

        Event::listen(ResponsePrepared::class, function (ResponsePrepared $event) use ($key, $value) {
            $headers = collect($event->response->headers->all())
                ->reject(fn ($value, $key) => in_array($key, ['date', 'x-powered-by', 'cache-control', 'expires', 'set-cookie']))
                ->all();

              if ($event->response->getStatusCode() === 302) {
                  return;
              }

            $cacheValue = [
                'content' => $value,
                'headers' => $headers,
                'status' => $event->response->getStatusCode(),
            ];

            $this->getDefaultExpiration()
                ? $this->cache->put($key, $cacheValue, now()->addMinutes($this->getDefaultExpiration()))
                : $this->cache->forever($key, $cacheValue);
        });

to prevent any 302 code responses not to be statically cached and it works fine.

I am not sure if this is a bug from my code or statamic itself. but it should be nice if there was an option in the config to exclude certain html status codes from static cache via statamic/static_cache.php configuration.

I have also notice that there is also this issue here that seems to be similar to mine but instead with 404 error

How are you registering your custom middleware that handles the redirect?

I suspect it's being loaded after our static caching middleware returns the cached response, so the request never reaches your middleware.

[artisanbarista]

I am registering in Kernel.php

    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\GeoRedirect::class,
        ],

        'api' => [
            'throttle:api',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

[duncanmcclean]

Could you try sorting the middleware using the $middlewarePriority proprerty?

If that doesn't work, instead of registering it like you are now, can you try adding this to your AppServiceProvider (it should prepend your middleware so it runs before the static caching one):

app('router')->prependMiddlewareToGroup('web', GeoRedirect::class);
