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.
