6 Plack::Loader::Delayed - Delay the loading of .psgi until the first run
7
9 plackup -s Starlet -L Delayed myapp.psgi
10
12 This loader delays the compilation of specified PSGI application until
13 the first request time. This prevents bad things from happening with
14 preforking web servers like Starlet, when your application manipulates
15 resources such as sockets or database connections in the master startup
16 process and then shared by children.
17
18 You can combine this loader with "-M" command line option, like:
19
20 plackup -s Starlet -MCatalyst -L Delayed myapp.psgi
21
22 loads the module Catalyst in the master process for the better process
23 management with copy-on-write, however the application "myapp.psgi" is
24 loaded per children.
25
26 Starman since version 0.2000 loads this loader by default unless you
27 specify the command line option "--preload-app" for the starman
28 executable.
29
31 Web server developers can make use of "psgi_app_builder" attribute
32 callback set in Plack::Handler, to load the application earlier than
33 the first request time.
