my old blog had urls this: http://ali.dj/blog/unlimited-fps-in-unity-editor/comment-page1 etc.

when article valid following unnecessary strip out parts , parameters after url.

this http://ali.dj/blog/unlimited-fps-in-unity-editor/comment-page1

or http://ali.dj/blog/unlimited-fps-in-unity-editor/comment-page1?ref=foo

becomes http://ali.dj/blog/unlimited-fps-in-unity-editor

currently i've got catch-all route redirect user error-page

how can strip out unnecessary parts?

here's router.js use articles:

this.route('blog', { 'path' : 'blog/'}, function() {    this.route('post', { 'path' : ':permalink' })   this.route('not-found', { 'path' : 'not-found'}) });  // error routes this.route('not-found', { path : '/not-found'}) this.route('catch-all', { path : '/*path'})  // redirects not-found
