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.
