Are you asking about the query string (the part after the question mark)? You don't need to do anything about that. Unless you give other instructions, mod_rewrite will stash any existing query in a safe place, do all its stuff, and then quietly reappend the query without change.
Second paragraph deleted because g1 types faster than I do.
