📛 NAME

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

🚀 Quick Reference

Use Case	Command	Description
File‑based sessions (DB_File)	tie %hash, 'Apache::Session::Flex', $id, { Store => 'DB_File', Lock => 'Null', Generate => 'MD5', Serialize => 'Storable' };	Uses a Berkeley DB file for storage, no locking, MD5 IDs, and Storable serialisation.
PostgreSQL sessions	tie %hash, 'Apache::Session::Flex', $id, { Store => 'Postgres', Lock => 'Null', Generate => 'MD5', Serialize => 'Base64' };	Stores sessions in PostgreSQL with Base64‑encoded serialisation and no locking.
MySQL sessions	tie %hash, 'Apache::Session::Flex', $id, { Store => 'MySQL', Lock => 'MySQL' ... };	Uses MySQL as both storage and lock manager (config required).
Plain files	tie %hash, 'Apache::Session::Flex', $id, { Store => 'File', Lock => 'Null' ... };	Stores each session as a separate file on disk.
Custom modules	tie %hash, 'Apache::Session::Flex', $id, { Store => 'MyCustomStore', Lock => 'MyLock' ... };	Plug in your own Apache::Session::* module for any backend.

📝 SYNOPSIS

   Store     => 'DB_File',
   Lock      => 'Null',
   Generate  => 'MD5',
   Serialize => 'Storable'
};

# or

tie %hash, 'Apache::Session::Flex', $id, {
   Store     => 'Postgres',

📖 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 serialisation 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.
