103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
This module implements Dancer 2 session engine based on L files. |
105
|
|
|
|
|
|
|
|
106
|
|
|
|
|
|
|
This backend can be used in single-machine production environments, but two |
107
|
|
|
|
|
|
|
things should be kept in mind: The content of the session files is not |
108
|
|
|
|
|
|
|
encrypted or protected in anyway and old session files should be purged by a |
109
|
|
|
|
|
|
|
CRON job. |

=head1 CONFIGURATION |
112
|
|
|
|
|
|
|
|
113
|
|
|
|
|
|
|
The setting B should be set to C in order to use this session |
114
|
|
|
|
|
|
|
engine in a Dancer2 application. |
115
|
|
|
|
|
|
|
|
116
|
|
|
|
|
|
|
Files will be stored to the value of the setting C, whose default |
117
|
|
|
|
|
|
|
value is C. |
118
|
|
|
|
|
|
|
|
119
|
|
|
|
|
|
|
Arguments for the L and L objects can be |
120
|
|
|
|
|
|
|
given via the C and C. If not provided, they default to |
121
|
|
|
|
|
|
|
C<< snappy => 1, croak_on_bless =>1 >> and C<< refuse_objects => 1, validate_utf8 => 1 >>, respectively. |
