Do you need a redirect or a rewrite for that?

Which URL appears in links on the page?

Which URL should users actually see?

What is the file called on the server itself?

[kloo]

I try %{query_string} but it will redirect to

[forum.example.com...] (something like that)

actually, I want:

People suff [forum.example.com...]
then 301 redirect to [forum.example.com...]

and
tid=3--> 3
page=2 --> 2
ex=1 --> 1

What code have you tried?

Adding a question mark to the end of the target URL will strip the parameter string from the end of the new URL.
