[squid-users] Determining unique clients in Squid

[Veiko Kukk]

Hi,

I have been trying to understand, how does Squid determine different 
clients, but it is not clear from the documentation. I guess this does 
not depend entirely on IP address, right? Otherwise all clients behind 
NAT would be considered as single client.

Reason behind this is that I'd like to configure a forward proxy for 
(mostly) binary files caching. All requests have Authorization headers 
(API key) and come from single IP address (localhost, python 
application, not generic web browser).

client <https> squid ssl_bump to see inside https <https> remote cloud 
storage

http://wiki.squid-cache.org/SquidFaq/InnerWorkings#What_are_private_and_public_keys.3F
"Private objects are associated with only a single client whereas a 
public object may be sent to multiple clients at the same time."

I wonder if it would be possible to use Squid for effectively cache 
larger objects locally with this type of configuration?

Best regards,
Veiko
