=head1 NAME
Apache::Session::Store::MySQL - Store persistent data in a MySQL database
=head1 SYNOPSIS
use Apache::Session::Store::MySQL;
my $store = new Apache::Session::Store::MySQL;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);
=head1 DESCRIPTION
Apache::Session::Store::MySQL fulfills the storage interface of Apache::Session.
Session data is stored in a MySQL database.
=head1 SCHEMA
To use this module, you will need at least these columns in a table
called 'sessions', or another table name if you provide the TableName
argument:
id char(32) # or however long your session IDs are.
a_session blob # or varbinary if you plan to use a big session (>64k after serialization)
To create this schema, you can execute this command using the mysql program:
CREATE TABLE sessions (
id char(32) not null primary key,
a_session blob
);
If you use some other command, ensure that there is a unique index on the
table's id column.
=head1 CONFIGURATION
The module must know what datasource, username, and password to use when
connecting to the database. These values can be set using the options hash
(see Apache::Session documentation). The options are:
=over 4
=item DataSource
=item UserName
=item Password
=item TableName
=item Handle
=back
Example:
tie %hash, 'Apache::Session::MySQL', $id, {
DataSource => 'dbi:mysql:database',
UserName => 'database_user',
Password => 'K00l',
TableName => 'sessions'
};
Instead, you may pass in an already-opened DBI handle to your database.
tie %hash, 'Apache::Session::MySQL', $id, {
Handle => $dbh
};
