</Controller::Foo>
Allows you to run Perl code in a CGI environment derived from your L<Catalyst>
context.
+B<*WARNING*>: do not export L<CGI> functions into a Controller, it will break
+with L<Catalyst> 5.8 onward.
+
If you just want to run CGIs from files, see L<Catalyst::Controller::CGIBin>.
=head1 CONFIGURATION
-C<$your_controller->{CGI}{pass_env}> should be an array of environment variables
+C<< $your_controller->{CGI}{pass_env} >> should be an array of environment variables
or regular expressions to pass through to your CGIs. Entries surrounded by C</>
characters are considered regular expressions.
-Default is to pass the whole of C<%ENV>.
+C<< $your_controller->{CGI}{kill_env} >> should be an array of environment
+variables or regular expressions to remove from the environment before passing
+it to your CGIs. Entries surrounded by C</> characters are considered regular
+expressions.
-C<{CGI}{username_field}> should be the field for your user's name, which will be
-read from C<$c->user->obj>. Defaults to 'username'.
+Default is to pass the whole of C<%ENV>, except for C<MOD_PERL> (that is, the
+default C<kill_env> is C<[ 'MOD_PERL' ]>.
+
+C<< $your_controller->{CGI}{username_field} >> should be the field for your user's name, which will be
+read from C<< $c->user->obj >>. Defaults to 'username'.
