RE: [squid-users] Implication of positive_dns_ttl?

Did you get that rpm from updates.redhat.com? Ive been looking for an
updated squid rpm but mine shows 2.5stable1-2 (im not at work but im
pretty sure thats it). If not where? Otherwise im probably going to
rebuild an rpm for 2.5stable-latest.

What you can try is getting the SRPM for it and apply that patches. The
problem I found with some of RH rpms is the things they do to backport
fixes sometimes make patching difficult.

So what im going to try to do next week while at work is grab the SRPM
file and since it contains the SPEC file, ill use it to reference the
newer Squid sources to rebuild the RPM. If that fails, Ill check
rpmfind for an updated SRPM to get a working spec file and then
rebuild locally. Note if yours is an enterprise
system I doubt RH will support any changes you make to their loadout.

But if your just wanting that config option, get the SRPM, modify the SPEC
file and rebuild. The spec file contains the configuration flags used. More info at
www.rpm.org on how this is done.
