Create needed files
touch .env
cp docker-compose.override.yml.dist docker-compose.override.yml
Start php-cli (other containers will be started)
docker-compose run --rm php-cli
Inside the php-cli container install composer packages
composer install
The proxy url is available under http://localhost:10080 and the url to the php app is available under http://localhost:20080
The branch master contains a simple php script.
The branch symfony contains my test scenario with symfony.
If i use the simple php script variant, all looks fine. A call through the proxy creates a cache hit.

If symfony is used, the call through the proxy does not create a cache hit.
