NAME

Plack::Loader - (auto)load Plack Servers

SYNOPSIS

  # auto-select server backends based on env vars
  use Plack::Loader;
  Plack::Loader->auto(%args)->run($app);

  # specify the implementation with a name
  Plack::Loader->load('FCGI', %args)->run($app);

DESCRIPTION

Plack::Loader is a factory class to load one of Plack::Handler subclasses based on the environment.

AUTOLOADING

Plack::Loader->auto(%args) will autoload the most correct server implementation by guessing from environment variables and Perl INC hashes.

PLACK_SERVER
  env PLACK_SERVER=AnyEvent ...

Plack users can specify the specific implementation they want to load using the PLACK_SERVER environment variable.

PHP_FCGI_CHILDREN, GATEWAY_INTERFACE

If there's one of FastCGI or CGI specific environment variables set, use the corresponding server implementation.

%INC

If one of AnyEvent, Coro or POE is loaded, the relevant server implementation such as Twiggy, Corona or POE::Component::Server::PSGI will be loaded, if they're available.
