Meanwhile
seems better to start with simpler task like quiting the _s and _k part of
the url, because in a content centered site, the produce ugly urls and are
not much necesary. I will keep you posted.
you can get rid of the _s by enabling cookies. (app preferenceAt:
#useCookies put: true)
Pier will also try to remove the _k if possible (for example
http://mysite/blog,
http://mysite/about etc)
