After installing squid 3.1/3.2/3.3 on Fedora 18, Centos 6 or RHEL 6, the session helper file ext_session_acl is missing. Compiling from 3.3.source, it doesn't get compiled even when given argument to configure --enable-external-acl-helpers="session" . There is something about it will be compiled IF it is possible. Has anyone manage to use this helper on Red Hat?
Thanks, John.
Soultion: The problem was caused by a check for /usr/include/db.h which was missing, therefore the compile was skipped for session. Installed libdb-devel to fix this.
ls -al /usr/include/db.h
sudo yum provides /usr/include/db.h
sudo yum install libdb-devel
