 I need to pay attention to what configuration, please? 


thanks.

Well, you have

CONFIG proxy.config.cache.ram_cache_cutoff INT 4194304


However, that would still allow it to be cached. Make sure you have a disk 
cache, and that it is sufficiently large. Secondly, make sure the requests 
are not Range: requests, we don't cache partial objects.

Third, make sure the object is cacheable. You can control some behavior with

CONFIG proxy.config.http.cache.required_headers INT 2

(2 is the most conservative, requiring explicit Cache-Control or Expires 
headers).
