NAME
squid_session - Squid session tracking external acl group helper
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
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.
