[squid-users] Question about delay pools again

[Alex Samad]

So thought I would try it out

#
# Delay Pools
# http://wiki.squid-cache.org/Features/DelayPools
# http://www.serverwatch.com/tutorials/article.php/3357241/Reining-in-Bandwidth-With-Squid-Proxying.htm
delay_pools 1
delay_class 1 1

# 10Mb/s fille rate , 20Mb/s reserve
# 10485760/8 = 1310720
# 20971520/8 = 2621440
delay_parameters 1 1310720/2621440

# What to delay
acl Delay_ALL src all
acl Delay_Domain dstdomain -i "/etc/squid/lists/delayDom.lst"

delay_access 1 allow Delay_Domain


/etc/squid/lists/delayDom.lst
.windowsupdate.com


and I can just add domains to the file as needed
