NAME

CGI::Compile - Compile .cgi scripts to a code reference like ModPerl::Registry

SYNOPSIS

  use CGI::Compile;
  my $sub = CGI::Compile->compile("/path/to/script.cgi");

DESCRIPTION

CGI::Compile is an utility to compile CGI scripts into a code reference that can run many times on its own namespace, as long as the script is ready to run on a persistent environment.
NOTE: for best results, load CGI::Compile before any modules used by your CGIs.

RUN ON PSGI

Combined with CGI::Emulate::PSGI, your CGI script can be turned into a persistent PSGI application like:
  use CGI::Emulate::PSGI;
  use CGI::Compile;
  my $cgi_script = "/path/to/foo.cgi";
  my $sub = CGI::Compile->compile($cgi_script);
  my $app = CGI::Emulate::PSGI->handler($sub);
  # $app is a PSGI application

CAVEATS

If your CGI script has a subroutine that references the lexical scope variable outside the subroutine, you'll see warnings such as:
  Variable "$q" is not available at ...
  Variable "$counter" will not stay shared at ...
This is due to the way this module compiles the whole script into a big "sub". To solve this, you have to update your code to pass around the lexical variables, or replace "my" with "our". See also <http://perl.apache.org/docs/1.0/guide/porting.html#The_First_Mystery> for more details.
