Hi, We'd like to limit our bandwith / file type with using ACL and delay pool. Our Squid (2.6e21) is configured as a reverse proxy, in front of a apache server (2.2.3) - We don't have any error starting Squid but the delay pool seams not working. - If you use acl with http_deny directive, there no problem and files are not allowed to be download. - We also tried to use delay_class 1 with ACL all and it's not working. Here you have the delay pool configuration: #ACL identifiant les fichiers hebdomadaires, mensuels et complets acl fichiers url_regex -i \^*ful25.m25$ \^*m25.m25$ \^*cur25.m25$ #Declaration des pools de gestion de bande passante delay_pools 2 #definition du pool concernant les fichiers volumineux. #Chaque poste d'un réseau dispose de 30Ko/s de bande passante, #un sous réseau de classe C dispose de 50 Ko/s #et la totalité des postes demandant ce type de fichiers disposent de 1Mo/s delay_class 1 3 delay_access 1 allow fichiers delay_access 1 deny all delay_parameters 1 1048576/1048576 50200/50200 30720/50200 #definition du pool pour les autres fichiers #Aucune limite n'est positionnée pour le moment delay_class 2 3 delay_access 2 deny fichiers delay_access 2 allow all delay_parameters 2 -1/-1 -1/-1 -1/-1 Here you have squid -v command result: [root] # squid -v Squid Cache: Version 2.6.STABLE21 configure options: '--build=x86_64-redhat-linux-gnu' '--host=x86_64-redhat-linux-gnu' '--target=x86_64-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--includedir=/usr/include' '--libdir=/usr/lib64' '--libexecdir=/usr/libexec' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--exec_prefix=/usr' '--bindir=/usr/sbin' '--libexecdir=/usr/lib64/squid' '--localstatedir=/var' '--datadir=/usr/share' '--sysconfdir=/etc/squid' '--enable-epoll' '--enable-snmp' '--enable-removal-policies=heap,lru' '--enable-storeio=aufs,coss,diskd,null,ufs' '--enable-ssl' '--with-openssl=/usr/kerberos' '--enable-delay-pools' '--enable-linux-netfilter' '--with-pthreads' '--enable-ntlm-auth-helpers=SMB,fakeauth' '--enable-external-acl-helpers=ip_user,ldap_group,unix_group,wbinfo_group' '--enable-auth=basic,digest,ntlm' '--enable-digest-auth-helpers=password' '--with-winbind-auth-challenge' '--enable-useragent-log' '--enable-referer-log' '--disable-dependency-tracking' '--enable-cachemgr-hostname=localhost' '--enable-underscores' '--enable-basic-auth-helpers=LDAP,MSNT,NCSA,PAM,SMB,YP,getpwnam,multi-domain-NTLM,SASL' '--enable-cache-digests' '--enable-ident-lookups' '--enable-follow-x-forwarded-for' '--enable-wccpv2' '--enable-fd-config' '--with-maxfd=16384' 'build_alias=x86_64-redhat-linux-gnu' 'host_alias=x86_64-redhat-linux-gnu' 'target_alias=x86_64-redhat-linux-gnu' 'CFLAGS=-D_FORTIFY_SOURCE=2 -fPIE -Os -g -pipe -fsigned-char' 'LDFLAGS=-pie' Any idea or suggestion are really welcome :) Regards,
