NAME

       Apache::Session::Generate::MD5 - Use MD5 to create random object IDs

SYNOPSIS

	use Apache::Session::Generate::MD5;

	$id = Apache::Session::Generate::MD5::generate();

DESCRIPTION

       This module fulfills the ID generation interface of Apache::Session.  The IDs are generated using a two-round MD5 of a random number, the
       time since the epoch, the process ID, and the address of an anonymous hash.  The resultant ID number is highly entropic on Linux and other
       platforms that have good random number generators.  You are encouraged to investigate the quality of your system's random number generator
       if you are using the generated ID numbers in a secure environment.

       This module can also examine session IDs to ensure that they are, indeed, session ID numbers and not evil attacks.  The reader is
       encouraged to consider the effect of bogus session ID numbers in a system which uses these ID numbers to access disks and databases.

       This modules takes one argument in the usual Apache::Session style.  The argument is IDLength, and the value, between 0 and 32, tells this
       module where to truncate the session ID.  Without this argument, the session ID will be 32 hexadecimal characters long, equivalent to a
       128-bit key.

NAME

       Apache::Session::Flex - Specify everything at runtime

SYNOPSIS

	use Apache::Session::Flex;

	tie %hash, 'Apache::Session::Flex', $id, {
	   Store     => 'DB_File',
	   Lock      => 'Null',
	   Generate  => 'MD5',
	   Serialize => 'Storable'
	};

	# or

	tie %hash, 'Apache::Session::Flex', $id, {
	   Store     => 'Postgres',
	   Lock      => 'Null',
	   Generate  => 'MD5',
	   Serialize => 'Base64'
	};

	# you decide!

DESCRIPTION

       This module is an implementation of Apache::Session.  Unlike other implementations, it allows you to specify the backing store, locking
       scheme, ID generator, and data serializer at runtime.  You do this by passing arguments in the usual Apache::Session style (see SYNOPSIS).
       You may use any of the modules included in this distribution, or a module of your own making.  If you wish to use a module of your own
       making, you should make sure that it is available under the Apache::Session package namespace.

USAGE

       You pass the modules you want to use as arguments to the constructor.  The Apache::Session::Whatever part is appended for you: you should
       not supply it.  For example, if you wanted to use MySQL as the backing store, you should give the argument "Store =" 'MySQL'>, and not
       "Store =" 'Apache::Session::Store::MySQL'>.  There are four modules that you need to specify.  Store is the backing store to use.  Lock is
       the locking scheme.  Generate is the ID generation module.  Serialize is the data serialization module.

       There are many modules included in this distribution.  For each role, they are:

	Store:
	   MySQL
	   Postgres
	   DB_File
	   File

	Lock:
	   Null
	   MySQL
	   Semaphore

	Generate:
	   MD5

	Serialize:
	   Storable
	   Base64
	   UUEncode

       In addition to the arguments needed by this module, you must provide whatever arguments are expected by the backing store and lock manager
       that you are using.  Please see the documentation for those modules.
