Title: Hi HN,<p>I&#x27;ve noticed recently Facebook has started using URLs which seem to include encoded information.<p>For example, this URL to Vice:
<a href="https:&#x2F;&#x2F;www.facebook.com&#x2F;VICE&#x2F;posts&#x2F;pfbid02XdVziPTwhmPU9XzBqkRvU5o7NPXUicAJgVy8kf1a1W51hU7EmgMmCigo9rZWxCjDl" rel="nofollow">https:&#x2F;&#x2F;www.facebook.com&#x2F;VICE&#x2F;posts&#x2F;pfbid02XdVziPTwhmPU9XzBq...</a><p>It&#x27;s a pretty URL with some kind of hash at the end beginning with &quot;pfbid.&quot;<p>Whereas they used to look like basic sharded URLs:
<a href="https:&#x2F;&#x2F;www.facebook.com&#x2F;random.username&#x2F;posts&#x2F;10208327509806082" rel="nofollow">https:&#x2F;&#x2F;www.facebook.com&#x2F;random.username&#x2F;posts&#x2F;1020832750980...</a><p>Is this for more targeted tracking on posts and links being shared, a new sharding scheme, a combination of both, or something else entirely?<p>Appreciate any insights the community can provide.
