SYNOPSIS

  use Plack::App::CGIBin;
  use Plack::Builder;

  my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app;
  builder {
      mount "/cgi-bin" => $app;
  };

  # Or from the command line
  plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app'

DESCRIPTION

This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server.

HOW IT WORKS

If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web server mode and no performance benefit is achieved.

The default mechanism to determine if a given file is a Perl script is as follows:

• Check if the filename ends with ".pl". If yes, it is a Perl script.
• Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl script.

You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument.

For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you can do:

  my $app = Plack::App::CGIBin->new(
      root => "/path/to/cgi-bin",
      exec_cb => sub { 1 },
  )->to_app;

to always force the execute option for any files.
