[wp-hackers] creating plugin urls which function as a callback?

[Burobjorn]

Hi,

Which filter or action do I need before I can use new urls such as 
mywordpressinstall.test/new/?

Basically I would like to create new urls for my plugin and have the url 
function as a callback. Any clues on how to achieve this or does this 
does not make any sense?

grtz
