i want to have parameter in friendly urls way, have done it with query string but this is not what i want
below is my link
http://www.example.org/category-name/sub-category/post-name-goes-here
and want to have link in template like this
http://www.example.org/category-name/sub-category/post-name-goes-here/parameter
it should still load the same single page but with parameter so i can use condition in single page template
how i can ignore this using rewrite rule or any other method?
