我想在同一臺機器的php應用程序前面使用squid作爲反向緩存代理，並且永遠不會讓用戶到達後端，始終加載過時的緩存在背景中。魷魚2.7和客戶端頁眉max-age = 0
我使用在端口80編譯魷魚2.7 Stable9與Centos的6.3（x86_64的）的自和Apache + PHP是在同一臺機器與所述端口8000
的阿帕奇+ PHP的響應頭將其發送到魷魚：
header('Cache-Control: max-age=10, stale-while-revalidate=15, stale-if-error=20');
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
當我問一個頁面魷魚，第一次重新驗證並在下一次使用總是陳舊的，但這個工程與Firefox WebDevelopersTools延伸DISABLE CACHE緩存選項。
不同的是，當高速緩存未禁用，客戶端發送緩存控制：最大年齡= 0和的If-Modified-由於和魷魚總是和重新驗證連接到後端。
在魷魚3.2它如預期使用ignore-cc但在2.7中沒有這樣的選項。
這裏是我的squid.conf：
# http_port public_ip:port accel defaultsite= default hostname, if not provided
http_port 80 accel defaultsite=mydomain.com
# IP and port of your main application server (or multiple)
cache_peer 127.0.0.1 parent 8000 0 no-query originserver name=main
cache_peer_domain main mydomain.com
# Do not tell the world that which squid version we're running
httpd_suppress_version_string on
# Remove the Caching Control header for upstream servers
header_access Cache-Control deny all
# log all incoming traffic in Apache format
logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh
access_log /usr/local/squid/var/logs/squid.log combined all
cache_effective_user squid
refresh_pattern nocache=true 0 0% 0
icp_port 0
我想在PHP應用程序選擇緩存時間，從來沒有讓用戶看到重新驗證的等待時間，這就是爲什麼我使用的是2.7版本與陳舊，同時，重新驗證。與緩存請求

例如使用禁用緩存（我希望發生的事情）：此處描述
