<session></session>

Creates a session bound scope. The session is identified by a session key, given as an argument to the session tag. The session key could be e.g. a value generated by &roxen.unique-id; which is then transported by form variables. An alternative which often is more convenient is to use the variable client.session (provided by this module) together with the <force-session-id> tag and the feature to set unique browser id cookies in the http protocol module (located under the server ports tab).

Attributes

id
id=string
This attribute is required.

The key that identifies the session. Could e.g. be a name, an IP adress, a cookie or the value of the special variable client.session provided by this module (see above).

life
life=number (900)

Determines how many seconds the session is guaranteed to persist on the server side.

If the module isn't configured to use a shared database, then values over 900 means that the session variables will be moved to a disk based database when they have not been used within 900 seconds.

force-db

If used, the session variables will be immediatly written to the database. Otherwise session variables are only moved to the database when they have not been used for a while (given that they still have "time to live", as determined by the life attribute).

Setting this flag will increase the integrity of the session, since the variables will survive a server reboot, but it will also decrease performance somewhat.

If the module is configured to use a shared database then sessions are always written immediately, regardless of this flag.

scope
scope=name (session)

The name of the scope that is created inside the session tag.
