=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, I )

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