=head1 SYNOPSIS
package My::PSGI;
use base Lemonldap::NG::Common::PSGI;
# See Lemonldap::NG::Common::PSGI
...
sub router {
my ( $self, $req ) = @_;
# Do something and return a PSGI response
# NB: $req is a Lemonldap::NG::Common::PSGI::Request object
if ( $req->accept eq 'text/plain' ) { ... }
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Body lines' ] ];
}
