=head3 $Response->Include( $path, %args )
ASP4's C<$Response> object offers 3 different include methods.
<!-- Normal SSI-style Include -->
<!-- #include virtual="/includes/page.asp" -->
If you want to supply arguments to the included ASP script you can use C<< $Response->Include($path, \%args) >>
# Add the output of C</includes/page.asp> to the current output buffer:
my %args = ( foo => "bar" );
$Response->Include( $Server->MapPath("/includes/page.asp"), \%args );
C<\%args> is optional.
Within the included ASP script, C<\%args> is accessible like this:
<%
my ($self, $context, $args) = @_;
%>
=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.
