=head1 NAME

Rose::DBx::Cache::Anywhere - get Apache::DBI behaviour without Apache

=head1 DESCRIPTION

This class is used by Rose::DBx::AutoReconnect.

The author uses

Rose::DB with Catalyst under both the Catalyst dev server and

FastCGI and found that the standard Rose::DB::Cache behaviour

did not work well with those environments.

=head1 METHODS

=head2 prepare_db( I<rose_db>, I<entry> )

Overrides default method to always ping() dbh if not running

under mod_perl.

    my ( $self, $db, $entry ) = @_;

        }

        # if this a dummy lx office dbh, don't try to actually prepare this.

        }
