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.
