Markup Regions and empty files

[Manaus]

I set up the config file to load _main.php for each page.

$config->appendTemplateFile = '_main.php';

Now, I need to have one page without template loaded, for ajax purposes. Can I put some instruction on my empty.php template to not load _main?

Thank you very much
