[squid-users] Windows caching

[Jasper Van Der Westhuizen]

Hi all

I am trying to tweak my configuration to better catch Windows 10
 updates. I download the file manually so at the first log entry I see
the TCP_HIT/206, then after the download is completed I get
TCP_HIT/200. But If I download the file again I get another TCP_HIT/206
and the file is downloaded again.

Any idea why it's doing this?
