[squid-users] Seemingly incorrect behavior: squid cache getting filled up on PUT requests

I am using Squid Cache:
Version 3.HEAD-20140127-r13248

My cache dir is configured to use rock (Large rock with SMP):
cache_dir rock /mnt/squid-cache 256000 max-size=4194304

My refresh pattern is permissive to cache all objects:
refresh_pattern . 129600 100% 129600 ignore-auth

I uploaded 30 GB of data via squid cache with PUT requests.
From storedir stats(squidclient mgr:storedir) it seems like each PUT
is occupying 1 slot in rock cache.

Is this a known bug? PUT requests should not increase cache usage right?
