Please consider compiling in "null" storage module support. This is done by passing --enable-storeio="aufs,coss,diskd,null,ufs" to configure. null allows the user to configure no disk caching at all, which is useful when squid's other features (proxying, logging) but not caching are required in a DMZ environment.
should be done in 2.5.STABLE1-1.
Sorry, I can't see the fix. From squid-2.5.STABLE1-1.src.rpm, dated Jan 16 2003, squid.spec still uses --enable-storeio="aufs,coss,diskd,ufs".
I put up squid-2.5.STABLE1-3.i386.rpm and squid-2.5.STABLE1-3.src.rpm on ftp://people.redhat.com/fenlason/ The binary was built on 8.0 because I don't have any 7.3 systems to hand. It has two changes: one is the null storage module, another is a tweak to the number of maximum file descriptors it can open. If you can check it out, I'll see if I can slip it into the next beta. It may be too late, though.
