Web Caching

All,

1st what caching solutions are you all using?

We are considering Squid with WCCP, but are looking for details on what lines in the configurations we need to be concerned with, how best to define redirections ..

I am wanted check and see if any one has deployed Squid with WCCP or WCCP2 in your environment and if so what "/etc/squid/squid.conf" line items do I need to consider when setting this up?

Also, what is the best placement within the network, we are essentially provide ISP services for 18 school districts and our pipe to the Internet is 70mbps going to 100mpbs by summer.

We have Cisco 7206's as "outside" and "inside" routers, we have a Content Filter, and a Packeteer all running into a 3Com Core Builder. Now we want to through Squid into this mix and not kill the network.

We are looking for recommendations, suggestions and configuration or design ideas.
This is very new area for us, but is sounds like it might help with dropping the utilization of our internet if we configure it correctly..


I built a new Fedora Box, 3.2ghz processor, 3 GB Ram, 73gb drive, dual 1GB ethernet.

Any thoughts, or ideas appreciated.

Re: Web Caching

Here you have a link to WCCP:

I would consider the use of a squid "cluster", maybe, using heartbeat. You can also have independent squid caches as peers and a network load balancer infront to balance the load, allow client grow and provide failover.

Re: Web Caching

Squid is the best way to go, with all caches in the round-robin being peered. Enable transparent proxying using iptables, on the same box where squid is.

Re: Web Caching

Ivan and raq, thank you, we have to put some designs together and hopefully size things adequately.

I know what round robin but not the foggiest way in which to "do it", perhaps we will use a load balancing switch or some other mechanism when we reach that point.

Re: Web Caching

We have gotten this running,

Squid with WCCP/TPROXY running under FC6.

saving about 12% bandwidth, dropped from flatlining 70Mg pipe to around 58Mg avg.. Cool.
