Why have attachment links an additional dateline component?

[ThorstenA]

Why is there a &dateline= in the attachmente links in vbulletin 4? Just curious.

To be honest, I've never understood that either. If you remove the dataline part from the URL, you will still see the image. :/

Yes, I have removed all the dataline components in postbit_attachment and attachmentbit tempates when I saw the component in my google search results. This is not good for seo.

I can understand that a dateline can be good once an attachment would be updated. But in this case, the attachment should get a new id. And even if not (which is not possible due to the auto-increase mysql configuration), only in this case an additional dateline would do.

Improvement request to remove the component (everyone feel free to vote):

I could be wrong here, but I believe its to get over browser caching issues if the attachment is updated.
