Preloading middleware / response cache in Laravel? - php

Question

I have some response values I'm caching using middleware in Laravel, like this:
public function handle($request, Closure $next)
{
$domain = parse_url($request->headers->get('origin'), PHP_URL_HOST);
$key = 'request|'.$domain.'|dashboard';
return cache()->rememberForever($key, function () use ($request, $next) {
return $next($request);
});
}
If values within that response function change, I'd like to reset the cache, and ideally pre-set it before any user experiences the load time.
However I'm not entirely sure how to go about that given that I'm setting the cache value as a closure - $next($request). Inherently, it is caching the actual serialized response.
Is there an easy way for me to mock this response programatically?
Edit: to clarify - the above functionality works fine, what I'd like is something like below:
public function resetCache($key)
{
// Clear out old cache:
cache()->forget($key);
// Preload new cache:
cache()->set($key, function ($request, $next) {
return $next($request);
});
}
Obviously the function above won't work since I have no context on $request or $next.
I'm starting to think I'm going about this the wrong way, inherently.

Try this:
public function handle($request, Closure $next)
{
$domain = parse_url($request->headers->get('origin'), PHP_URL_HOST);
$key = 'request|'.$domain.'|dashboard';
$response = $next($request);
if($response !== Cache:get($key)) {
Cache:forget($key);
}
return cache()->rememberForever($key, function () use ($reponse) {
return $response;
});
}
