Wicket and custom URL handling

Hi,

I am search for customizing the URL-Handling in wicket. There are not so
many articles about that.
I would like to handle all URLs starting with /east or /west with one page.
Other possible URLs:
- /east/services/help
- /east/services/
or
- /east/services/help?param=value

Also there should be some pages, which are mounted normally /error ->
ErrorPage.class

Also I dont want parameters like ?0 ?1 ... on the custom URLs and I
would like to submit WicketForms to /east/services/

Which is the best approach to implement this?
