session-id

Generate a COUNTER compliant user ID and session ID in the fields user_id and session_id.

The user ID can be one of the following, by order of priority :

• the user login (default field: login)
• the cookie ID (default field: cookie)
• both the IP (default field: host) and the user agent (default field: user-agent)

The session ID is generated by concatenating the date, hour of day, and user ID.

Default fields can be changed with the Session-ID-Fields header.
