Middleware for session management

## NAME

Plack::Session - Middleware for session management

## SYNOPSIS

```
  # Use with Middleware::Session
  enable "Session";
  # later in your app
  use Plack::Session;
  my $app = sub {
      my $env = shift;
      my $session = Plack::Session->new($env);
      $session->id;
      $session->get($key);

  };
```

## DESCRIPTION

This is the core session object, you probably want to look at Plack::Middleware::Session, unless you are writing your own session middleware component.

## METHODS

- **new ( $env )**

  The constructor takes a PSGI request env hash reference.

- **id**

  This is the accessor for the session id.

### Session Data Management

These methods allows you to read and write the session data like Perl's normal hash.

- **get ( $key )**

  - **set ( $key, $value )**

  - **remove ( $key )**

  - **keys**

  - **session**, **dump**

  ### Session Lifecycle Management

- **expire**

  This method can be called to expire the current session id.
