add virtuall page

Basically I need to make a page which is not regular page or post.
Basically what I need is to make a link, example

https://www.my_wordpress.com/ma_page

my plugin would have to check what the current link is

oh! its ‘ma_page’

lets load a template from plugin (not from theme)

Bascil functionality:

function virtual_page() {
$url_name = check_url();
if ($url_name == ‘my_page’) {
/* load the content from plugin themplate */
ob_start();
include ABSPATH . ‘wp-content/plugins/virtual_page/page.php’;
$content = ob_get_contents();
ob_get_clean();

/* and here display the content on virtual page */
/* how ? */

}

}

of course I don’t need page in admin section!!!!!!!

thanks for clues
