[wp-hackers] internal redirects

[John Bloch]

Or, since it seems you only need this on pages or single posts, why not use:

global $wp_query;
if( $wp_query->post->post_name == get_option( 'my_plugin_slug' ) ) {
     add_action('wp_loaded', 'my_plugin_check');
     add_shortcode('public-gallery', 'my_plugin');
}
