POE::Session is a Perl module for event driven abstract state machine.

SYNOPSIS

# Import POE::Session constants.
use POE::Session;

POE::Session->create(

# Inline or coderef states.
inline_states => {
state_one => &coderef_one,
state_two => sub { ... },
},

# Plain and mapped object states.
object_states => [
$object_one => [ state_three, state_four, state_five ],
$object_two => { state_nine => method_nine },
],

# Plain and mapped package states.
package_states => [
$package_one => [ state_six, state_seven, state_eight ],
$package_two => { state_ten => method_ten },
],

# Parameters for the sessions _start state.
args => [ argument_zero, argument_one, ... ],

# Initial options. See the option() method.
options => %options,

# Change the sessions heap representation.
heap => [ ],
);
Other methods:
# Retrieve a sessions unique identifier.
$session_id = $session->ID;

# Retrieve a reference to the sessions heap.
$session_heap = $session->get_heap();

# Set or clear session options.
$session->option( trace => 1, default => 1 );
$session->option( trace );

# Create a postback, then invoke it and pass back additional
# information.
$postback_coderef = $session->postback( $state_name, @state_args );
$postback_coderef->( @additional_args );

# Or do the same thing synchronously
$callback_coderef = $session->callback( $state_name, @state_args );
$retval = $callback_coderef->( @additional_args );

POE::Session combines a runtime context with an event driven state machine. Together they implement a simple cooperatively timesliced thread.
Sessions receive their timeslices as events from POE::Kernel. Each event has two fields, a state name and a session identifier. These fields describe the code to run and the context to run it in, respectively.

Events carry several other fields which will be discussed in the "Predefined Event Fields" section.

States are re-entrant since they are invoked with their runtime contexts. Although its not usually necessary, this re-entrancy allows a single function to be bound to several different sessions, under several different state names.
As sessions run, they post new events through the Kernel. These events may be for themselves or other sessions, in which case they act as a form of inter-session communications. The Kernel can also generate events based on external conditions such as file activity or the passage of time.

POE provides some convenient built-in states with special meanings. They will be covered later on in the "Predefined States" section.

PHP::Session::DB is a Perl module to read / write PHP sessions stored in databases.

SYNOPSIS

use PHP::Session::DB;

my $session = PHP::Session::DB->new($id, { DBUSER => $dbuser, DBPASSWD => $dbpasswd, DBNAME => $dbname });

# session id
my $id = $session->id;

# get/set session data
my $foo = $session->get(foo);
$session->set(bar => $bar);

# remove session data
$session->unregister(foo);

# remove all session data
$session->unset;

# check if data is registered
$session->is_registered(bar);

# save session data
$session->save;

# destroy session
$session->destroy;

# create a new session, if not existent
$session = PHP::Session->new($new_sid, { %dbvars, create => 1 });

PHP::Session::DB provides a way to read / write PHP4 sessions stored on databases, with which you can make your Perl application session shared with PHP4.

Session Directory Tool provides a multicast session directory manager.
SDR is a session directory tool designed to allow the advertisement and joining of multicast conferences on the Mbone. It was originally modelled on sd written by Van Jacobson at LBNL, but implements a later version of the session description protocol than sd does.
SDR was originally written under the MICE and MERCI projects at UCL by Mark Handley who now works for ISI. SDR will continue to be maintained on a limited basis as part of the infrastructure for conferencing on the CAIRN testbed network and the EC MECCANO project.
Many many fixes and improvements to SDR have been contributed by Bill Fenner and Van Jacobson. Security features were implemented by Edmund Whelan and Goli Montasser-Kohsari at UCL.
Enhancements:
- new application media type for session directories
- fixed byte ordering of headers on intel machines
- fixed IP6 address allocation for unix IP6 stacks
- Authentication and encryption code fixed to allow for extra space for IPv6 addresses
- Added IPv6 flags to configure scripts "--enable-ipv6"

DB_eSession provides a class that securely stores PHP sessions in a MySQL database.
DB_eSession is a feature-packed PHP class that stores session data in a MySQL database rather than files. It is powerful, designed with security in mind, and is easy to utilize.
The code contains lots of comments, and it comes with full documentation and examples of how to use the class including a basic authentication login/logout process.
It includes member functions useful (to webmasters) for monitoring or viewing, deleting, and altering sessions validity for the case of locking one or more sessions upon detection of unauthorized use.
Main features:
- General features:
- Stores session data in a MySQL table using PHPs built-in session handler.
- Built-in handling of session expiration and cleanup.
- Supports the changes of session related configuration settings (inc. PHP5).
- Allows for normal or persistent MySQL database connections.
- Access to opened MySQL resource connection to use in your script.
- Accepts a passed database resource link to use as the DB connection.
- Supports session IDs between 12 and 32 characters long.
- Custom or changeable database, table and column names.
- An option to create new session IDs (you supply, class or PHP builds).
- Can initiate buffered output (using ob_start) within the class.
- A session_start() automatically initiated within the class.
- Can send Cache-Control: header output within the class (fixes IE6 bug).
- Ability to retrieve a specific sessions expiration date and time.
- Retrieve current session life setting in seconds or minutes.
- Retrieve a numeric total of the number of active and inactive sessions in table.
- Facility to make assignment and retrieval of session variables easier.
- Ability to create manual URIs and links that includes session name and ID.
- The ability to retrieve what the MySQL server version number is.
- An adequate form of encode/decode member functions are included and used automatically when libmcrypt is not installed.
- Security features:
- Standard user inactivity time-out handled automatically.
- Absolute user logoff time-out capability (session will be terminated no matter what after a number of designated minutes/seconds have elapsed).
- Ability to lock and unlock a particular session or all sessions. When a session is made locked it is immediately not available for use.
- User to session verification using IP address and browser information.
- Security level (code) clearance for each session/web page.
- Encrypt/decrypt as desired each session field.
- Encrypt/decrypt an extra session field to compare against original (to detect against possible tampering).
- Encrypt/decrypt the whole session data in the table (essentially obscuring session variable names in table). Can be used in combination with per session field encryption, resulting in double encryption security.
- A new encryption Initialization Vector is created every time values change.
- Ability to manually delete a particular session or all sessions.
- The users IP address and web browser is recorded as part of the session for tracing information.
- Other features:
- Support for multiple language error and warning messages.
- Support of a default language as well as current active language settings.
- Basic or detailed (with SQL syntax) error/warning reporting.
- Buffered error and warning messages.
- Option for class to stop execution or not upon encountering an error/warning. Class can display errors/warnings automatically or control in your script.
- Can select font color and size separately for error and warning messages.
- Code has lots of comments and formatted within 82 characters wide.
- Full documentation (only provided in English) is included.
- Code use examples provided, including a basic authentication (login/logout) process.
- SQL text file provided for creating the MySQL session table.
