Attachment rewrite issues

I have some issues with attachment rewrites. I first noticed when I was grabbing them to embed some mp3's into threads.

I use the following settings, and store the files in the filesystem:
Custom; [forum_title]/[attachment_id]/[original_filename]

When I view attachments from a thread or the attachment manager I get this URL:
http://www.dragonninja.co.uk/attachm...kethestand.mp3

When I view the same attachment from editpost.php I get this URL:
http://www.dragonninja.co.uk/attachm...1&d=1209910528

First of all, shouldn't the editpost URL be rewritten too? The second issue is, I don't think this rewrite is actually correct?

The attachment id is 4977, I believe the 'd' is part of the original URL (d=xxx) - but I have no idea where the 1208218630 comes from. It is 10 characters long, such as the d=xxx in the original URL, but different characters.

So something is up here, am I right?

If I change the URL format to what I believe to be correct, it still works:
http://www.dragonninja.co.uk/attachm...kethestand.mp3

We potentially have 3 possible URL's for the same files, so I am guessing we could end up with duplicate content issues.

Let me know what you guys think!

Hello Matthew ,

During the editpost or newpost as attachements are newly processed i donot think that rewriting them on that stage is possible. Maybe it is possible but it will nto be efficient.

1208218630 this is the unix date of the attachments processed time

Ah I see, my custom URL does not contain a parameter for "unix date" so will I be able to remove it?

Also if I understand you correctly, you are saying they cannot be rewritten at the point of adding the attachment? I could understand that, but this is an old thread with old attachments.

Any idea why the two unix dates in the URL's are different? And do you think it will be possible to fix this and consolidate the URL's?

vBulletin creates attachment URLs on client side with javascript in this case, so they are not processed by vBSEO.

This parameter is required to avoid caching the image when it's modified (attachment reuploaded).

Ah I see, hopefully there will be a way around this in future. Thanks.
