Persist variable across all requests

[Manol]

Is there a way to persist variables across different users without being logged and without writing the variable result to a file.

In my case the admin publishes several vehicles of different branches, these my differ every day so I've used LazyCron to check active branches every two hours, to avoid querying DB each time a user look for vehicles, I tried putting the result in a session variable but it doesn't work between different users.

 I could write the branches every two hours to a file and read it every time but, is there a better way to do it?

Thank you.

I would look at using the WireCache functionality.

This is far more than I expected, awesome pw, thank you.

I'm using PW 2.6.1

$markas_cached = $cache->get("marcas", "+1 second", function($pages) {
            $markas = ["DAF", "IVECO", "LIEBHERR", "MAN", "MERCEDES", "RENAULT", "SCANIA", "SCHMITZ", "VOLVO"];
            return $markas;
}); 
echo json_encode($cache->get("marcas"));
echo json_encode($markas_cached);

I've changed array values manually $markas = ["DAF", "IVECO"] with different times with the template way but the array values never change. Any ideas.

are you caching a plain array or a Pagearray

Have you checked the database to see what is cached there in the caches table and what the expiration date is?

have you tried clearing the cache using $cache->delete(...)..

Do you use any sort of markup caching? TemplateCache, ProCache?
