Squid-cache clustering

[wlagmay@xxxxxxxxxxxxx]

Hi all,

I just want to know if theres other way to cluster 2 or more Squid-cache/proxy? 
My idea of clustering 2 or more proxy is by using a layer 7 switch, define a
common IP on the switch that will simoultaneously checks multiple proxy server.

Any Idea is welcome and highly appreciated.

Thank you very much
