NAME

       Plack::Loader::Delayed - Delay the loading of .psgi until the first run

SYNOPSIS

	 plackup -s Starlet -L Delayed myapp.psgi

DESCRIPTION

       This loader delays the compilation of specified PSGI application until the first request time. This prevents bad things from happening with
       preforking web servers like Starlet, when your application manipulates resources such as sockets or database connections in the master
       startup process and then shared by children.

       You can combine this loader with "-M" command line option, like:

	 plackup -s Starlet -MCatalyst -L Delayed myapp.psgi

       loads the module Catalyst in the master process for the better process management with copy-on-write, however the application "myapp.psgi"
       is loaded per children.

       Starman since version 0.2000 loads this loader by default unless you specify the command line option "--preload-app" for the starman
       executable.

DEVELOPERS

       Web server developers can make use of "psgi_app_builder" attribute callback set in Plack::Handler, to load the application earlier than the
       first request time.
