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.
