Pass argument in URL

Hi,

We have a URL http://www.example.com/artistsatmyclub, this path is created for a view.
Now there is requirement where I have to pass an argument to this page to fetch certain artists.
ex. http://www.example.com/artistsatmyclub&topLevel=category will show only category artists
Similarly there are some other filters.
The code works fine if I pass the argument using "&topLevel=category"

Is there a way to pass the argument without "&topLevel="
so instead of http://www.example.com/artistsatmyclub&topLevel=category we want the URL to be http://www.example.com/artistsatmyclub/category

Your help is much appreciated.

Thanks
