Looking to redirect all URLs which look similar to this:
https://www.example.com/discussion/topix/random-page-title.133760/posts/1255466/rate?rating=13&_Token=78139%2C1464617730%2Ca42dfb1db7e54b51db1879075650aaf4a3c3323a
to
https://www.example.com/discussion/topix/random-page-title.133760/
Basically removing the following from the URL:
posts/1255466/rate?rating=13&_Token=78139%2C1464617730%2Ca42dfb1db7e54b51db1879075650aaf4a3c3323a
They are parts of an old system.
