This module implements a session engine based on JSON files. Session
are stored in a session_dir as JSON files. The idea behind this module
was to provide a transparent session storage for the developer.
This backend is intended to be used in development environments, when
looking inside a session can be useful.
It's not recommended to use this session engine in production
environments.
Typically you would want to use Dancer::Session::YAML for this, which
comes in core, but a demand for a faster-but-still-file-based session
backend arose, and thus you now have JSON. :)
CONFIGURATION
The setting session should be set to JSON in order to use this session
engine in a Dancer application.
Files will be stored to the value of the setting session_dir, whose
default value is appdir/sessions.
Here is an example configuration that use this session engine and
stores session files in /tmp/dancer-sessions
Creates a new object, runs flush and returns the object.
flush
Writes the session information to the session dir.
retrieve
Retrieves session information from the session dir.
destroy
Deletes session information from the session dir.
reset
Wipes the sessions directory, forcing a test for existence of the
sessions directory next time a session is created. It takes no
argument.
This is particulary useful if you want to remove the sessions directory
on the system where your app is running, but you want this session
engine to continue to work without having to restart your application.
