Hello Squid users, Can anyone explain, why Squid doesn't cache the objects with max-age values below 60 seconds? For example:
$ http_proxy="127.0.0.1:3128" curl --head "http://sandbox.comnet.local/ cgi-bin/hello.cgi" && date HTTP/1.1 200 OK Date: Mon, 22 Aug 2016 11:31:16 GMT Server: Apache Cache-Control: max-age=60 Content-Type: text/plain X-Cache: MISS from gentoo.comnet.uz Via: 1.1 gentoo.comnet.uz (squid/3.5.20) Connection: keep-alive Mon Aug 22 16:31:19 UZT 2016 --- $ http_proxy="127.0.0.1:3128" curl --head "http://sandbox.comnet.local/ cgi-bin/hello.cgi" && date HTTP/1.1 200 OK Date: Mon, 22 Aug 2016 11:31:23 GMT Server: Apache Cache-Control: max-age=60 Content-Type: text/plain X-Cache: MISS from gentoo.comnet.uz Via: 1.1 gentoo.comnet.uz (squid/3.5.20) Connection: keep-alive Mon Aug 22 16:31:26 UZT 2016 No problems with values above 60 seconds. For example: $ http_proxy="127.0.0.1:3128" curl --head "http://sandbox.comnet.local/ cgi-bin/hello.cgi" && date HTTP/1.1 200 OK Date: Mon, 22 Aug 2016 11:36:06 GMT Server: Apache Cache-Control: max-age=70 Content-Type: text/plain X-Cache: MISS from gentoo.comnet.uz Via: 1.1 gentoo.comnet.uz (squid/3.5.20) Connection: keep-alive Mon Aug 22 16:36:09 UZT 2016 --- $ http_proxy="127.0.0.1:3128" curl --head "http://sandbox.comnet.local/ cgi-bin/hello.cgi" && date HTTP/1.1 200 OK Date: Mon, 22 Aug 2016 11:36:06 GMT Server: Apache Cache-Control: max-age=70 Content-Type: text/plain Age: 5 X-Cache: HIT from gentoo.comnet.uz Via: 1.1 gentoo.comnet.uz (squid/3.5.20) Connection: keep-alive Mon Aug 22 16:36:11 UZT 2016 As you can see, time difference between origin server and localhost is 3 seconds (UZT is +5 offset).
