They met a major problem: No current release of squid can share its disk-cache with any external application (including other squid). You can link a SAN-type share and allocate a space for each squid to read/write as its cache_dir. But that does not solve the object-duplication. And I believe some SAN have RAID backup? that may cause problems by itself. Duplication can be prevented or at least reduced by balancing the squid as sibling peers with proxy-only option, and preferring sibling-fetch over direct-fetch. Amos
