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.
