NAME

Apache2::ASP::Base - Base class for ASP engines

SYNOPSIS

  package MyASP;

  # Use whatever Apache2::* and APR::* modules are necessary:
  
  sub handler : method
  {
    my ($class, $r) = @_;
    
    # We function best as an object:
    my $s = $class->SUPER::new( $ENV{APACHE2_ASP_CONFIG} );
    
    # What Apache2::ASP::Handler is going to handle this request?
    my $handler_class = $s->resolve_request_handler( $r->uri );
    if( $handler_class->isa('Apache2::ASP::UploadHandler') )
    {
      # We use the upload_hook functionality from Apache::Request
      # to process uploads:
      my $upload_hook = sub {
        my ($upload, $data) = @_;
        # Handle upload hook here...
      };
      $s->{q} = Apache2::ASP::CGI->new( $r, $upload_hook );
    }
    else

      $s->{q} = Apache2::ASP::CGI->new( $r );
    }# end if()
    
    # Get our subref and execute it:
    my $handler = $s->setup_request( $r, $s->{q} );
    my $status = eval { $handler->( ) };
    if( $@ )
    {
      warn "ERROR AFTER CALLING \$handler->( ): $@";

DESCRIPTION

METHODS

new( $config )

Returns a new Apache2::ASP::Base object using the Apache2::ASP::Config object passed in as $config.

setup_request( $r )

Creates a new request instance, based on the information about the request gleaned from $r - an Apache2::RequestRec object (or something that behaves like one anyway).

Returns a subroutine reference.

Execute like:

  my $ref = $asp->setup_request( $r );
  
  # A normal request:
  $ref->( 0 );
  # or
  $ref->( );
  
  # A subrequest (i.e. as in the case of an include):
  $ref->( 1 );
