14 Catalyst::Engine::CGI - The CGI Engine
18 A script using the Catalyst::Engine::CGI module might look like:
23 use lib '/path/to/MyApp/lib';
28 The application module (C<MyApp>) would use C<Catalyst>, which loads the
29 appropriate engine module.
33 This is the Catalyst engine specialized for the CGI environment (using the
34 C<CGI> and C<CGI::Cookie> modules). Normally Catalyst will select the
35 appropriate engine according to the environment that it detects, however you
36 can force Catalyst to use the CGI engine by specifying the following in your
39 use Catalyst qw(-Engine=CGI);
41 The performance of this way of using Catalyst is not expected to be
42 useful in production applications, but it may be helpful for development.
50 This config parameter contains the C<CGI> object.
