Plack::Handler - Connects PSGI applications and Web servers

       Plack::Handler defines an adapter (connector) interface to adapt plackup and Plack::Runner to various
       PSGI web servers, such as Apache2 for mod_perl and Standalone for HTTP::Server::PSGI.

       It is an empty class, and as long as they implement the methods defined as an Server adapter interface,
       they do not need to inherit Plack::Handler.

       If you write a new handler for existing web servers, I recommend you to include the full name of the
       server module after Plack::Handler prefix, like Plack::Handler::Net::Server::Coro if you write a handler
       for Net::Server::Coro. That way you'll be using plackup command line option like:

         plackup -s Net::Server::Coro

       that makes it easy to figure out which web server you're going to use.

       new
             $server = FooBarServer->new(%args);

           Creates  a  new  adapter object. %args can take arbitrary parameters to configure server environments
           but common parameters are:

           port    Port number the server listens to.

           host    Address the server listens to. Set to undef to listen any interface.

       run
             $server->run($app);

           Starts the server process and when a request comes in, run the PSGI application passed in $app in the
           loop.

       register_service
             $server->register_service($app);

           Optional interface if your server  should  run  in  parallel  with  other  event  loop,  particularly
           AnyEvent. This is the same as "run" but doesn't run the main loop.
