  -type string
        type of cache, lru or lfu, weak (default "lru")
  -verbose

curl --request PUT --data '1' http://localhost:8080/cache/1
curl --request PUT --data '2' http://localhost:8080/cache/2
curl --request PUT --data '3' http://localhost:8080/cache/3
curl --request PUT --data 'some new value' http://localhost:8080/cache/3

To retrieve the key

curl --request GET localhost:8080/cache/3

Prometheus metrics

curl --request GET localhost:8080/metrics
