Hello all, This is a copy of a post I put up via Google Groups. Since I wasn't subscribed at the time I'm not sure if it went through or not. I've searched through the archives a bit and can't quite find what I'm looking for. I'm trying to use some of the HTTP violating features offered by squid. Specifically my refresh pattern is: refresh_pattern . 10080 100% 20160 override-expire override-lastmod ignore-no-cache ignore-private I read that to mean that a document will be kept fresh for a minimum of 10080 minutes (7 days) and a maximum of 20160 minutes (14 days), or 100% of it's age. Further, any explicit Expire header should be ignored, and the Last Modified header will be ignored if it falls out of the range above. Finally, if a no-cache or private setting is used in the Cache-control header, it will be ignored. Have I got that mostly straight? Is there some fundamental problem with my description? I'm running squid 2.6.STABLE2 on FreeBSD 6.1. My configuration options are below. You'll noticed I did not turn on --disable-http-violations. Any help? configure options: '--bindir=/usr/local/sbin' '--sbindir=/usr/local/sbin' '--datadir=/usr/local/etc/squid' '--libexecdir=/usr/local/libexec/squid' '--localstatedir=/usr/local/squid' '--sysconfdir=/usr/local/etc/squid' '--enable-removal-policies=lru heap' '--disable-linux-netfilter' '--disable-linux-tproxy' '--disable-epoll' '--enable-auth=basic ntlm digest' '--enable-basic-auth-helpers=NCSA PAM MSNT SMB YP' '--enable-digest-auth-helpers=password' '--enable-external-acl-helpers=ip_user session unix_group wbinfo_group' '--enable-ntlm-auth-helpers=SMB' '--enable-coss-aio-ops' '--enable-storeio=ufs diskd null coss' '--disable-carp' '--disable-wccp' '--disable-ident-lookups' '--enable-kqueue' '--enable-err-languages=English' '--enable-default-err-language=English' '--prefix=/usr/local' 'i386-portbld-freebsd6.1' 'LDFLAGS=' 'CFLAGS=-O2 -fno-strict-aliasing -pipe ' 'CPPFLAGS=' 'host_alias=i386-portbld-freebsd6.1' 'build_alias=i386-portbld-freebsd6.1' 'target_alias=i386-portbld-freebsd6.1' 'CC=cc' -- David Olbersen (x2152) iGuard Engineer St. Bernard Software 15015 Avenue of Sciences San Diego, CA 92127
