NAME ^

Apache2::ASP::ApplicationStateManager - The $Application object

SYNOPSIS ^

  # In a handler, ASP script or your GlobalASA:
  $Application->{some_gobal_thing} = "A new value";
  
  # ...then, in all requests to the server...
  my $val = $Application->{some_global_thing};
  
  # You can also store objects:
  $Application->{some_object} = My::Thing->new( ... );
  
  # You can access the current $Application through the context also:
  my $app = Apache2::ASP::HTTPContext->current->application;

DESCRIPTION ^

All $Application objects are instances of one or another subclass of Apache2::ASP::ApplicationStateManager.

Apache2::ASP::ApplicationStateManager is the base class for all ApplicationStateManagers.

The $Application object is implemented as a simple, blessed hash with no special magick going on anywhere. $Application is not a blessed hash and does not depend on special semantics, nor does it expect special treatment.

Storage

By default, when it is time to store the contents of the $Application object for later retrieval, the venerable Storable module is used. The resulting binary blob is stored in the database referred to in the data_connections/application part of the config.

Configuration

The apache2-asp-config.xml configuration file should contain a section like the following:

  <?xml version="1.0" ?>
  <config>
    ...
    <data_connections>
      ...
      <application>
        <manager>Apache2::ASP::ApplicationStateManager::SQLite</manager>
        <dsn>DBI:mysql:dbname:hostname</dsn>
        <username>sa</username>
        <password>s3cr3t!</password>
      </application>
      ...
    </data_connections>
    ...
  </config>

Database Storage

The table that the $Application object is stored in has the following structure:

  CREATE TABLE  asp_applications (
    application_id    varchar(100) NOT NULL,
    application_data  blob,
    PRIMARY KEY  (application_id)
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Different databases will have different ways of spelling that, but the structure is clear.

PUBLIC METHODS ^

save( )

Stores the object in the database. Returns true.
