一个squid配置文档的注释

# NETWORK OPTIONS(有关的网络选项)
# -----------------------------------------------------------------------------
http_port 3128 #代理端口
icp_port 3130 #icp端口
# OPTIONS WHICH AFFECT THE NEIGHBOR SelectION ALGORITHM(作用于邻居选择算法的有关选项)
#-----------------------------------------------------------------------------
#禁止缓存
hierarchy_stoplist cgi-bin ?
hierarchy_stoplist -i ^https:\\ ?
acl QUERY urlpath_regex -i cgi-bin \? \.asp \.php \.jsp \.cgi
acl denyssl urlpath_regex -i ^https:\\
no_cache deny QUERY
no_cache deny denyssl
#上面几个就是说碰到URL中有包含cgi-bin和以https:\\开头的都不要缓存,
#更有asp、cgi、php等动态脚本也不要缓存,
#因为这些脚本通常都是动态更新的,这样数据不同步。
#更有
https://
开通的不缓存是因为一般我们进行电子商务交易,
#例如银行付款等都是采用这个的,假如把信用卡号什么缓存那不是很危险。
# OPTIONS WHICH AFFECT THE CACHE SIZE(定义cache大小的选项)
# -----------------------------------------------------------------------------
cache_mem 8 MB #额外使用内存量,可根据您的系统内存在设定,一般为实际内存的1/3
cache_swap_low 90 #最低缓存百分比
cache_swap_high 95 ##最高缓存百分比,就是上面那个额外内存的使用百分比
maximum_object_size 4096 KB #单个文档最大缓存大小,超过这个大小将不缓存
maximum_object_size_in_memory 8 KB #在内存中单个文档最大缓存大小,超过这个大小将不缓存到内存中
#有DNS正反解所得到的IP存在缓存区的大小,这样能够加快解析速度
ipcache_size 1024
ipcache_low 90
ipcache_high 95
fqdncache_size 1024
# LOGFILE PATHNAMES AND CACHE DIRECTORIES(定义日志文档的路径及cache的目录)
# -----------------------------------------------------------------------------
#  ; ; ; ; ; ;
#  那个aufs只有在编译的时候加入--enable-async-io那个选项才有支持,
#  至于目录所在地和所占用的磁盘大小则请视您的主机情况而定,
#  而后面dir1, dir2则是两个次目录的大小,通常16 256或64 64皆可,
#  一般来说,数字最好是16的倍数,据说性能会比较好啦!
cache_dir aufs /Cache1 100 16 256
cache_dir aufs /Cache2 100 16 256

refresh_pattern . 0 20% 4320
#上面第一行假如网址开头是ftp的话,那么在一天(1440分钟)后,
#假如proxy再次取用这个档案时,则cache内的数据会被更新!
# TIMEOUTS(超时)

#连接到其他机器的最大尝试时间

# MISCELLANEOUS(杂项)
# -----------------------------------------------------------------------------
# TAG: logfile_rotate
#squid会定期的将日志文档更名并打包。
#比如正在使用的日志文档为access.log,squid会将其更名并打包为access.log.1.gz;
#过了一定时间后,squid又会将access.log.1.gz更名为access.log.2.gz
#并将当前的日志文档更名并打包为access.log.1.gz,以此循环。
#logfile_rotate指定的数字即为打包并备份的文档的数量,当达到这一数目时,
#squid将删除最老的备份文档。默认值为1 0。假如想手动来进行这些操作,
#能够用logfile_rotate 0来取消自动操作。
logfile_rotate 4

# TAG: snmp_port
# Squid can now serve statistics and status information via SNMP.
# By default it listens to port 3401 on the machine. If you don''t
# wish to use SNMP, set this to "0".
