You didn’t understand. I know about what you talked but I’m asking for option where ID of post would be sent as a GET and then it will redirect to topic page with hash and topic ID (like in examples from vBulletin and SMF I posted above)

As I said above, I want to migrate from SMF and in SMF’s URLs there are IDs of posts and I want to redirect to correct one. When there is only one page of topic, then there is no problem with redirection that ends with named anchor, but for longer topics I can’t find number of page where post appear.
