Apache2::ASP::Handler
Base class for all Apache2::ASP handlers

Apache2::ASP::Handler - Base class for all Apache2::ASP handlers



NAME

Apache2::ASP::Handler - Base class for all Apache2::ASP handlers


SYNOPSIS


  package MyHandler;

  

  use strict;

  use base 'Apache2::ASP::Handler';

  

  sub run {

    my ($s, $asp, @args) = @_;

    

    $asp->response->Write("Hello, world!.");

  }# end process_request()

  

  1;# return true:

Access MyHandler via the URL /handlers/MyHandler on your website.


DESCRIPTION

Apache2::ASP::Handler offers an ``in-between'' ASP environment in which there is no Perl embedded within HTML (via <% and %> tags) but you still get the ASP objects ($Request, $Response, $Session, $Server and $Application).

Handlers are useful for things like form processing when no HTML content is sent back to the client (because the client is redirected to another ASP instead).


METHODS

The following methods are intended for subclasses of Apache2::ASP::Handler.

run( $self, $asp, @args)

Works just like the example in the synopsis.

register_mode( %args )

Allows your Handler class to handle ``mode=xxx'' requests for other Handlers.

Example:


  package MyHandler;

  

  use base 'SomeDefaultHandler';

  

  __PACKAGE__->register_mode(

    name    => 'mymode',

    handler => \&do_mymode,

  );

  

  # Accessible via URLs such as /handler/SomeDefaultHandler?mode=mymode

  sub do_mymode

  {

    my ($Session, $Request, $Response, $Server, $Application) = @_;

    

    # ... do stuff ...

    $Response->Write("mymode is successful!");

  }# end do_mymode()

Any call to /media/file123.gif?mode=mymode will execute your do_mymode() method.

This is useful for generating image thumbnails - i.e. /media/file123.gif?mode=thumb&max_w=100&max_h=80

The rest is left as an exercise for the reader.
