mod_rewrite and GET parameters

[Energetik]

Hi.

Mission:
pass a GET parameter to PHP

Example:
site.com/news/alias.html?amp

in template:
<?php
if (isset($_GET['amp']))
{
echo 'Hooray!';
}
?>

cool! works!

BUT
how to make url more beautiful ?

for example:
site.com/news/amp/alias.html

maybe Contao can help for this?
