鱿鱼代理不缓存任何东西

  • 772

鱿鱼.conf：

http_access allow all

# Squid normally listens to port 3128
http_port 3128 accel defaultsite=localhost no-vhost

cache_peer localhost parent 80 0 no-query originserver name=myAccel
cache_peer_access myAccel allow all

# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /usr/local/var/cache/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /usr/local/var/cache/squid

Squid 3.2.9，通过 Homebrew 安装在 OSX 上

localhost: ~ $ squid -v
Squid Cache: Version 3.2.9
configure options:  '--disable-debug' '--disable-dependency-tracking' '--prefix=/usr/local/Cellar/squid/3.2.9' '--localstatedir=/usr/local/var' 'CC=cc' 'CXX=c++' 'PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig'

开始鱿鱼squid -f squid.conf -d 2 -N

上游正在返回有效的 Cache-Control 标头，我已通过访问 Google Chrome 26 中的页面并在 Chrome Dev Tools 中观看来验证这些标头是正确的。

localhost: ~ $ curl -s -o /dev/null --dump-header /dev/stdout  http://localhost/test.php
HTTP/1.1 200 OK
Date: Tue, 16 Apr 2013 21:29:33 GMT
Server: Apache/2.2.22 (Unix) DAV/2 PHP/5.3.15 with Suhosin-Patch mod_ssl/2.2.22 OpenSSL/0.9.8r
X-Powered-By: PHP/5.3.15
Cache-Control: max-age=60, public
Content-Length: 16
Content-Type: text/html

但是当我通过 Squid 反向代理查询页面时，我总是会遇到缓存未命中的情况。

localhost: ~ $ curl -s -o /dev/null --dump-header /dev/stdout  http://localhost:3128/test.php
HTTP/1.1 200 OK

Cache-Control: max-age=60, public
Content-Length: 16
Content-Type: text/html
X-Cache: MISS from localhost
Via: 1.1 localhost (squid/3.2.9)
Connection: keep-alive

我的配置有什么问题？

    哦，废话，我想通了。

    Squid 忽略不到一分钟或等于一分钟的缓存头。所以 max-age=60 被忽略了，但是 max-age=61 就像一个魅力。

    <?php
Header('Cache-Control: max-age=61');
