Ok, I have added this line of code > acl localnet src 192.168.1.0/24 just above where it lists all the safe ports. It appears to restart ok with these 2 lines enabled now. *http_access allow CONNECT wuCONNECT localnet http_access allow windowsupdate localnet* Now I thought I might try a test (not with windows yet); I tried to download an Nvida Driver 223 MB. I did that on one machine, and once that was complete, I tried it on another machine . . . it does not appear to be coming from the proxy cache as it is not any faster. To be sure I was going through the proxy I set windows explorer connections to 192.168.1.6 and port 8080 on both machines. and I even changed the last http_access setting to: > http_access deny all . . . to make sure it was going through the proxy - and it was because web access was blocked until I changed it back to http_access *allow* all I tried a smaller file by downloading the latest Firefox install file (about 21 MB) and that was no faster either. I have a fairly advance router (MikroTik RB450G) that shows all the data going in & out the WAN cable. It was definitely not drawing from the proxy the 2nd time. Any Ideas why it is not caching -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/defined-localnet-to-mean-your-local-clients-tp4661726p4661728.html Sent from the Squid - Users mailing list archive at Nabble.com.
