No, requests are not directly mapped to filesystem. Instead md5 is taken
from the proxied URL and this hash is used to find response in cache.
Besides, the cached response has full header: for example, 404 response
may be cached. Also the response may be cached only if it was requested
no less than, e.g., 2 times for some time.
