Hi all,
Thanks for the responses.
I am using squid 3.1 on Ubuntu 12.04. For now I am just trying to
cache Apache's default "it works" page, which should be cache able. I
cannot use rebot here since my network is not connected to the
Internet.
I tried to do the configuration from scratch again using the guideline at
http://wiki.squid-cache.org/ConfigExamples/Reverse/BasicAccelerator
and here is the new config:
http_port 80 accel defaultsite=cona-server vhost
cache_peer 192.168.122.21 parent 80 0 no-query originserver name=myAccel
acl our_sites dstdomain cona-server
http_access allow our_sites
cache_peer access myAccel allow our_sites
cache_peer access myAccel deny all
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.1/8 0.0.0.0/32 ::1
acl SSL_ports port 443
acl Safe_ports port 80
acl Safe_ports port 21
acl Safe_ports port 443
acl Safe_ports port 70
acl Safe_ports port 210
acl Safe_ports port 1025-65535
acl Safe_ports port 280
acl Safe_ports port 488
acl Safe_ports port 591
acl Safe_ports port 777
acl CONNECT method CONNECT
http_access allow all
http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost
http_access deny all
http_port 3128
coredump_dir /var/spool/squid3
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880
refresh_pattern . 0 20% 4320
Now, I noticed a strange behavior. With this config, squid was saying
TCP_REFRESH_UNMODIFIED, then when I restarted squid, it said TCP_MISS.
Then I cleared the browser cache and then Squid said
TCP_REFRESH_UNMODIFIED again. Is this expected?
If you are testing by pressing the force-refresh button on the browser
it sends controls to Squid requiring the server be re-contacted with an
refresh check. The server appears to be sending back data identical to
the last lot and Squid detects the lack of change, logs
REFRESH_UNMODIFIED. The expected result is a 304 arriving at the browser
from Squid.
