C<\%args> is optional.

Within the included ASP script, C<\%args> is accessible like this:

  <%
    my ($self, $context, $args) = @_;
  %>

=head3 $Response->TrapInclude( $path, %args )

Or if you need to capture the result of executing an ASP script and use it within
a variable, use C<< $Response->TrapInclude($path, \%args) >>

  # Capture the output of C</includes/page.asp>:
  my %args = ( foo => "bar" );
  my $html = $Response->TrapInclude( $Server->MapPath("/includes/page.asp"), \%args );

C<\%args> is optional.

Within the included ASP script, C<\%args> is accessible like this:

  <%
    my ($self, $context, $args) = @_;
  %>

=head2 $Session

The C<$Session> object is an instance of a subclass of L<ASP4::SessionStateManager>
(depending on your website's configuration).

The C<$Session> object is a simple blessed hashref and should be used like a hashref.

Examples:

=head3 Set a session variable

  $Session->{foo} = "bar";

  $Session->{thing} = {
    banana  => "yellow",
    cherry  => "red",
    peach   => "pink,
  };

=head3 Get a session variable

  my $foo = $Session->{foo};

=head3 $Session->save()

Called automatically at the end of every successful request, causes any changes
to the C<$Session> to be saved to the database.

=head3 $Session->reset()

Call C<< $Session->reset() >> to clear all the data out of the session and save 
it to the database.

=head2 $Config

The ASP4 C<$Config> object is stored in a simple JSON format on disk, and accessible
everywhere within your entire ASP4 application as the global C<$Config> object.

If ever you find yourself in a place without a C<$Config> object, you can get one
like this:

  use ASP4::ConfigLoader;
  my $Config = ASP4::ConfigLoader->load();

See L<ASP4::Config> for full details on the ASP4 C<$Config> object and its usage.

=head2 $Stash

The C<$Stash> is a simple hashref that is guaranteed to be the exact same hashref
throughout the entire lifetime of a request.

Anything placed within the C<$Stash> at the very beginning of processing a request -
such as in a RequestFilter - will still be there at the very end of the request -
as in a RegisterCleanup handler.

Use the C<$Stash> as a great place to store a piece of data for the duration of
a single request.

=head1 DATABASE

While ASP4 B<does not require> its users to choose any specific database (eg: MySQL or PostgreSQL)
or ORM (object-relational mapper) the B<recommended> ORM is L<Class::DBI::Lite>
since it has been completely and thoroughly tested to be 100% compatible with ASP4.

For full documentation about L<Class::DBI::Lite> please view its documentation.

B<NOTE:> L<Class::DBI::Lite> must be installed in addition to ASP4 as it is a separate library.

=head1 ASP4 QuickStart

Here is an example project to get things going.

In the C<data_connections.main> section of C<conf/asp4-config.json> you should have
something like this:

  ...
    "main": {
      "dsn":              "DBI:mysql:database_name:data.mywebsite.com",
      "username":         "db-username",
      "password":         "db-pAsswOrd"
    }
  ...

Suppose you had the following tables in your database:

  create table users (
    user_id     bigint unsigned not null primary key auto_increment,
    email       varchar(200) not null,
    password    char(32) not null,
    created_on  timestamp not null default current_timestamp,
    unique(email)
  ) engine=innodb charset=utf8;
  
  create table messages (
    message_id    bigint unsigned not null primary key auto_increment,
    from_user_id  bigint unsigned not null,
