I don't think those sites use mod_rewrite because an URl can be anything, including:
http://www.oijoij.com/eorier/eoroeir/oier/eorij.pl?terer=wer4334&oijo=weroo&jjjjj=123# (or much more complicated urls). Those sites (because there are more) just put the urls in a database, and assign an ID to each one. Then, a program (that can be made in any language) queries the database for the given ID, and get the long URL. Then it redirects to that URL and that's all. I have made such a program in perl but it is very very simple.
