Hey I'm not sure if you are use ini for configuration but here is how I'd do it if I had a:
module => blog
controller => article
action => list
// Parameter to get from the request in the controller
// Note that those are the defaults in case you don't provide any parameters in the url
sortBy => author
order => asc
page => 1
in the ini file:
; /www.exemple.com/blog/articles/author/desc/2
resources.router.routes.whateverroutname.route = /blog/articles/:sortBy/:order/:page
resources.router.routes.whateverroutname.defaults.module = blog
resources.router.routes.whateverroutname.defaults.controller = article
resources.router.routes.whateverroutname.defaults.action = list
resources.router.routes.whateverroutname.defaults.sortBy = author
resources.router.routes.whateverroutname.defaults.order = asc
resources.router.routes.whateverroutname.defaults.page = 1
Hope this helps :)
