Plack::Middleware::Session(3pm) User Contributed Perl Documentation Plack::Middleware::Session(3pm)
NAME
Plack::Middleware::Session - Middleware for session management
SYNOPSIS
use Plack::Builder;
my $app = sub {
my $env = shift;
my $session = $env->{'psgix.session'};
return [
200,
[ 'Content-Type' => 'text/plain' ],
[ "Hello, you've been here for ", $session->{counter}++, "th time!" ],
];
};
builder {
enable 'Session';
$app;
};
# Or, use the File store backend (great if you use multiprocess server)
# For more options, see perldoc Plack::Session::Store::File
builder {
enable 'Session', store => 'File';
$app;
};
DESCRIPTION
This is a Plack Middleware component for session management. By default it will use cookies to keep session state and store data in memory.
This distribution also comes with other state and store solutions. See perldoc for these backends how to use them.
It should be noted that we store the current session as a hash reference in the "psgix.session" key inside the $env where you can access it
as needed.
NOTE: As of version 0.04 the session is stored in "psgix.session" instead of "plack.session".
State
Plack::Session::State
This will maintain session state by passing the session through the request params. It does not do this automatically though, you are
responsible for passing the session param.
Plack::Session::State::Cookie
This will maintain session state using browser cookies.
Store
Plack::Session::Store
This is your basic in-memory session data store. It is volatile storage and not recommended for multiprocessing environments. However
it is very useful for development and testing.
Plack::Session::Store::File
This will persist session data in a file. By default it uses Storable but it can be configured to have a custom serializer and
deserializer.
Plack::Session::Store::Cache
This will persist session data using the Cache interface.
Plack::Session::Store::Null
Sometimes you don't care about storing session data, in that case you can use this noop module.
OPTIONS
The following are options that can be passed to this module.
state
This is expected to be an instance of Plack::Session::State or an object that implements the same interface. If no option is provided
the default Plack::Session::State::Cookie will be used.
store
This is expected to be an instance of Plack::Session::Store or an object that implements the same interface. If no option is provided
the default Plack::Session::Store will be used.
It should be noted that this default is an in-memory volatile store is only suitable for development (or single process servers). For a
more robust solution see Plack::Session::Store::File or Plack::Session::Store::Cache.
BUGS
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
cpan-RT.
