How to remove Cache-control header no-cache

My team and I are working on a Laravel API which communicates with a Vue.js frontend that uses the Apollo client to consume the GraphQL responses.

We have an issue with cache-control headers being added to the response.

Apollo cannot cache the contents because the response contains this header:

Cache-Control: no-cache, private

In php.ini, we have this to disable sending cache-control headers by PHP:

; Set to {nocache,private,public,} to determine HTTP caching aspects
; or leave this empty to avoid sending anti-caching headers.
; http://php.net/session.cache-limiter
session.cache_limiter =

In the nginx config we cannot find anything that is setting those headers. I checked the global nginx.conf and config file we setup in sites/available.

I can add this to the nginx config, but it will only add another header:

add_header Cache-Control "public";

Cache-Control: no-cache, private
Cache-Control: public

If this header is not coming from PHP or nginx, then where could it be coming from? And how can I remove or overwrite it?

Laravel 5.5
Folkloreatelier/laravel-graphql
PHP 7.1
nginx 1.14.0
Ubuntu 16.04

Solution

in any middleware you can use this example


    public function handle($request, Closure $next)
    {
        $response = $next($request);
        return $response instanceof \Symfony\Component\HttpFoundation\Response
            ? $response->header('pragma', 'no-cache')
                ->header('Cache-Control', 'no-store,no-cache, must-revalidate, post-check=0, pre-check=0')
                ->header('X-ANY-HEADER', 'any header value')
            : $response;
    }

but i do not know this fix your problem
