Laravel

The default web.php uses cookies. If we want a cached response we can't use cookies. Create a new middleware group in app/Http/Kernel.php

protected $middlewareGroups = [
    'stateless' => [
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],
    //...

After that create a new stateless.php file in your routes folder where all our cachable routes will be loaded. You can add it here app/Providers/RouteServiceProvider.php.

Route::middleware('stateless')
    ->namespace($this->namespace)
    ->group(base_path('routes/stateless.php'));

After that in your route return a response with the Cache-Control headers set.

Route::get('/nginx-cache-test', function () {
    sleep(1);
    return response('This response was generated at ' . date('H:i:s'))
        ->header('Cache-Control', 'public, max-age=0, s-maxage=1, stale-while-revalidate=60');
});
