How to setup cache in prod environment for download/update files?

Question

PHP

When updating a file in Symfony2 in the prod environment, the uploaded file is not updated.
In the dev environment everything works fine. What could be the problem ?

Answer 1

It's not a bug, it's a feature.
What is the meaning of cache then?
You can clear the cache with the command app/console cache:clear -e=prod (or hardcore rm -rf app/cache/*).
In general, you can disable the cache in the prod environment by commenting out the $kernel->loadClassCache(); in app.php, but you don't need to do that.

Answer 2

The problem is that you must manually clear the production cache. Because it's a production environment. Development is done in dev environment (suddenly, right?), and then tests are run (in production or test environment), and then deployed. Ideally, you don’t need to use the local environment at all, but if you want, you can do it:
or if your project uses the Symfony3 directory structure, then
bin/console cache:clear --e=prod
