Laravel 5.5 how to set Cache-Control HTTP header globally?

问题:

My Laravel application ist returning Cache-Control: no-cache, private HTTP header by default for each site. How can I change this behaviour?

P.S.: It is not a PHP.ini problem, because changing session.cache_limiter to empty/public does not change anything.

You can have a global middleware for that. something like:

<?php  namespace App\Http\Middleware;  use Closure;  class CacheControl {     public function handle($request, Closure $next)     {         $response = $next($request);          $response->header('Cache-Control', 'no-cache, must-revalidate');         // Or whatever you want it to be:         // $response->header('Cache-Control', 'max-age=100');          return $response;     } } 

then just register this as a global middleware in the Kernel file:

protected $middleware = [     ....     \App\Http\Middleware\CacheControl::class ];
