NAME

HTTP::Engine - Web Server Gateway Interface and HTTP Server Engine Drivers (Yet Another Catalyst::Engine)

SYNOPSIS

  use HTTP::Engine;
  my $engine = HTTP::Engine->new(
      interface => {
          module => 'ServerSimple',
          args   => {
              host => 'localhost',
              port =>  1978,
          },
          request_handler => 'main::handle_request',# or CODE ref
      },
  );
  $engine->run;

  use Data::Dumper;
  sub handle_request {
      my $req = shift;
      HTTP::Engine::Response->new( body => Dumper($req) );
  }

CONCEPT RELEASE

Version 0.0.x is a concept release, the internal interface is still fluid. It is mostly based on the code of Catalyst::Engine.

COMPATIBILITY

version over 0.0.13 is incompatible of version under 0.0.12.

using HTTP::Engine::Compat module if you want compatibility of version under 0.0.12.

version 0.0.13 is unsupported of context and middleware.

DESCRIPTION

HTTP::Engine is a bare-bones, extensible HTTP engine. It is not a socket binding server.

The purpose of this module is to be an adaptor between various HTTP-based logic layers and the actual implementation of an HTTP server, such as, mod_perl and FastCGI.

Internally, the only thing HTTP::Engine will do is to prepare a HTTP::Engine::Request object for you to handle, and pass to your handler's TBD method. In turn your TBD method should return a fully prepared HTTP::Engine::Response object.

HTTP::Engine will handle absorbing the differences between the environment, the I/O, etc. Your application can focus on creating response objects (which is pretty much what your typical webapp is doing)

INTERFACES

Interfaces are the actual environment-dependent components which handles the actual interaction between your clients and the application.

For example, in CGI mode, you can write to STDOUT and expect your clients to see it, but in mod_perl, you may need to use $r->print instead.

Interfaces are the actual layers that does the interaction. HTTP::Engine currently supports the following:

# XXX TODO: Update the list

HTTP::Engine::Interface::ServerSimple

HTTP::Engine::Interface::FastCGI

HTTP::Engine::Interface::CGI

HTTP::Engine::Interface::Test

for test code interface

HTTP::Engine::Interface::ModPerl

experimental

HTTP::Engine::Interface::Standalone

old style

Interfaces can be specified as part of the HTTP::Engine constructor:

  my $interface = HTTP::Engine::Interface::FastCGI->new(
    handler => ...
  );
  HTTP::Engine->new(
    interface => $interface
  )->run();

Or you can let HTTP::Engine instantiate the interface for you:

  HTTP::Engine->new(
    interface => {
      module => 'FastCGI',
      args   => {
        handler => ...
      }
    }
  )->run();

CONCEPT

HTTP::Engine is Not

    session manager
    authentication manager
    URL dispatcher
    model manager
    toy
    black magick

HTTP::Engine is

    HTTP abstraction layer
