@johnhiler: thanks for your reply, sorry I didn’t express clearly, I didn’t mean whether the attachment can be downloaded if registered or not, I mean, the permalink is dynamical and thus somewhat ugly, not that friendly in SEO.
Actually, I write a robots.txt rule in the root of http://www.dreamfreeblog.com like:
User-agent: *
Disallow: /bbs/?bb_attachment=*
but unexpectly, it didn’t work, the attachment link still be indexed. Do I need to write the rule in /bbs root?
and secondly, as the link like:
http://www.dreamfreeblog.com/bbs/ topic/18?bb_attachments=30&bbat=19
I don’t know how to write the robots.txt rule….
