NAME

Catalyst::Plugin::Session::Store::File - File storage backend for session data.

SYNOPSIS

    use Catalyst qw/Session Session::Store::File Session::State::Foo/;

    MyApp->config->{'Plugin::Session'} = {
        storage => '/tmp/session'
    };

    # ... in an action:
    $c->session->{foo} = 'bar'; # will be saved

DESCRIPTION

Catalyst::Plugin::Session::Store::File is an easy to use storage plugin for Catalyst that uses an simple file to act as a shared memory interprocess cache. It is based on Cache::FileCache.

METHODS

get_session_data
store_session_data
delete_session_data
delete_expired_sessions

These are implementations of the required methods for a store. See Catalyst::Plugin::Session::Store.

setup_session

Sets up the session cache file.

CONFIGURATION

These parameters are placed in the hash under the Plugin::Session key in the configuration hash.

storage

Specifies the directory root to be used for the sharing of session data. The default value will use File::Spec to find the default tempdir, and use a file named MyApp/session/data, where MyApp is replaced with the appname.

Note that the file will be created with mode 0640, which means that it will only be writeable by processes running with the same uid as the process that creates the file. If this may be a problem, for example if you may try to debug the program as one user and run it as another, specify a directory like /tmp/session-$>, which includes the UID of the process in the filename.

relative

Makes the storage path relative to $c-path_to>

namespace

The namespace associated with this cache. Defaults to an empty string if not explicitly set. If set, the session data will be stored in a directory called MyApp/session/data/<namespace>.

cache_depth

The number of subdirectories deep to session object item. This should be large enough that no session directory has more than a few hundred objects. Defaults to 3 unless explicitly set.

directory_umask

The directories in the session on the filesystem should be globally writable to allow for multiple users. While this is a potential security concern, the actual cache entries are written with the user's umask, thus reducing the risk of cache poisoning. If you desire it to only be user writable, set the 'directory_umask' option to '077' or similar. Defaults to '000' unless explicitly set.
