.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Shotgun loader delays the compilation and execution of your
application until the runtime. When a new request comes in, this forks
a new child, compiles your code and runs the application.
.PP
This should be an ultimate alternative solution when reloading with
Plack::Middleware::Refresh doesn't work, or plackup's default \f(CW\*(C`\-r\*(C'\fR
filesystem watcher causes problems. I can imagine this is useful for
applications which expects their application is only evaluated once
(like in-file templates) or on operating systems with broken fork
implementation, etc.
.PP
This is much like good old \s-1CGI\s0's fork and run but you don't need a web
server, and there's a benefit of preloading modules that are not
likely to change. For instance if you develop a web application using
Moose and DBIx::Class,
.PP
.Vb 1
\&  plackup \-MMoose \-MDBIx::Class \-L Shotgun yourapp.psgi
.Ve
.PP
would preload those modules and only re-evaluates your code in every
request.
