squid_session - Squid session tracking external acl group helper
squid_session [-t idle_timeout] [-b dbpath] [-a]
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
-t idletimeout (default 3600)
Specifies the session idle timeout timer.
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).
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.
Configuration example using the default automatic mode
external_acl_type session ttl=300 negative_ttl=0 children=1 concurrency=200 %LOGIN /usr/local/squid/libexec/squid_session
acl session external session
http_access deny !session
deny_info http://your.server/bannerpage?url=%s session
Then set up http://your.server/bannerpage to display a session startup page and then redirect the user back to the requested URL given in the url query parameter.
