Hi, Eliezer Croitoru I already sent the header in the first email. Is this the information you want ? ========= Squid 3.3.x ============ HTTP/1.1 200 OK Cache-Control: private Content-Length: 117991 Content-Type: text/html; charset=utf-8 Expires: Thu, 21 Nov 2013 03:12:14 GMT Server: Microsoft-IIS/7.5 Date: Thu, 21 Nov 2013 03:12:15 GMT X-Cache: MISS from localhost.localdomain Connection: close And after Amos's reply I check again the header of Squid-3.1 ========= Squid 3.1.x ============ HTTP/1.0 200 OK Cache-Control: private Content-Type: text/html; charset=utf-8 Expires: Tue, 26 Nov 2013 05:00:03 GMT Server: Microsoft-IIS/7.5 Date: Tue, 26 Nov 2013 05:00:04 GMT Content-Length: 117904 Age: 64 Warning: 110 squid/3.1.23 "Response is stale" (confused here too !) X-Cache: HIT from localhost.localdomain Connection: close In both case I used the same directives ignore-private and override-expire and same origin server. Squids also built in same server, the difference is only http service ports. Still don't know why squid 3.3 and 3.2 can't ignore-private and override-expire header.
