NAME
   CGI::PSGI - Adapt CGI.pm to the PSGI protocol

SYNOPSIS
     use CGI::PSGI;

     my $app = sub {
         my $env = shift;
         my $q = CGI::PSGI->new($env);
         return [ $q->psgi_header, [ $body ] ];
     };

DESCRIPTION
   This module is for web application framework developers who currently
   uses CGI to handle query parameters, and would like for the frameworks
   to comply with the PSGI protocol.

   Only slight modifications should be required if the framework is already
   collecting the body content to print to STDOUT at one place (rather
   using the print-as-you-go approach).

   On the other hand, if you are an "end user" of CGI.pm and have a CGI
   script that you want to run under PSGI web servers, this module might
   not be what you want. Take a look at CGI::Emulate::PSGI instead.

   Your application, typically the web application framework adapter should
   update the code to do "CGI::PSGI->new($env)" instead of "CGI->new" to
   create a new CGI object. (This is similar to how CGI::Fast object is
   initialized in a FastCGI environment.)

INTERFACES SUPPORTED
   Only the object-oriented interface of CGI.pm is supported through
   CGI::PSGI. This means you should always create an object with
   "CGI::PSGI->new($env)" and should call methods on the object.

   The function-based interface like "use CGI ':standard'" does not work
   with this module.

METHODS
   CGI::PSGI adds the following extra methods to CGI.pm:

 env
     $env = $cgi->env;

   Returns the PSGI environment in a hash reference. This allows
   CGI.pm-based application frameworks such as CGI::Application to access
   PSGI extensions, typically set by Plack Middleware components.

   So if you enable Plack::Middleware::Session, your application and plugin
   developers can access the session via:

     $cgi->env->{'plack.session'}->get("foo");

   Of course this should be coded carefully by checking the existence of
   "env" method as well as the hash key "plack.session".

 psgi_header
    my ($status_code, $headers_aref) = $cgi->psgi_header(%args);

   Works like CGI.pm's header(), but the return format is modified. It
   returns an array with the status code and arrayref of header pairs that
   PSGI requires.

   If your application doesn't use "$cgi->header", you can ignore this
   method and generate the status code and headers arrayref another way.

 psgi_redirect
    my ($status_code, $headers_aref) = $cgi->psgi_redirect(%args);

   Works like CGI.pm's redirect(), but the return format is modified. It
   returns an array with the status code and arrayref of header pairs that
   PSGI requires.

   If your application doesn't use "$cgi->redirect", you can ignore this
   method and generate the status code and headers arrayref another way.
