Problem with uri segments

[quote author="Dam1an" date="1240924454"]You could use routes for this
Make sure to check that segment 3 is a string, that segment 4 is either ASC or DESC, and that segments 5 and 6 are numeric

If I have some time later (and what I said above wasn;t very clear) i'll come up with an example[/quote]

Thanks. But I am not sure whether routing will help. Can you show any example for it? Also, my site is quite big so I was wondering if there is any another simpler solution for this.
