SYNOPSIS
squid_session [-t idle_timeout] [-b dbpath] [-a]DESCRIPTION
This helper maintains a concept of sessions by monitoring requests and timing out sessions if no requests have been seen for the idle timeout timer.Intended use is for displaying "terms of use" pages, ad popups etc.
- -t idletimeout (default 3600)
- Specifies the session idle timeout timer.
- -b dbpath
- Path to persistent database. If not specified the session details will be kept in memory only and all sessions will reset each time Squid restarts it's helpers (Squid restart or rotation of logs).
- -a
- Active mode. In this mode sessions are started by evaluating an acl with the argument LOGIN, or terminated by the argument LOGOUT.
Without this flag the helper automatically starts the session after the first request.
EXAMPLE
Configuration example using the default automatic mode
