Browseable session backend

Presentation

Browseable session backend (Apache::Session::Browseable) works exactly like Apache::Session::* corresponding module but add index that increase the speed of some operations. It is recommended in production deployments.

Note

Without index, LL::NG will have to retrieve all sessions stored in backend and deserialize then filter each of them.

The following table list fields to index for each session type:

List of fields to index by session type

Session Type Fields to index
Sessions (global) _whatToTrace _session_kind _utime ipAddr _httpSessionType user
Persistent sessions _session_kind _httpSessionType _session_uid ipAddr _whatToTrace
CAS sessions _cas_id pgtIou
SAML sessions _session_kind _utime _saml_id ProxyID _nameID _assert_id _art_id
OpenID Connect sessions _session_kind _utime

Note

If you have configured LemonLDAP::NG to use something other than _whatToTrace as the main session identifier, you must replace _whatToTrace with the new session field in the previous list

See Apache::Session::Browseable man page to see how use indexes.

Tip

It is advised to use separate session backends for standard sessions, SAML sessions and CAS sessions, in order to avoid unused indexes.
