So I really love the permalinks feature of Discourse.

For example, I’ve been collecting photos and videos at [https://fortmactech.com/riverbreak](https://fortmactech.com/riverbreak) – which forwards to the longer URL of the actual topic.

The problem I’m running into is that when that’s posted on Facebook and someone clicks it, Facebook appends its fbclid crap at the end. So the URL is something like:

```plaintext
https://fortmactech.com/riverbreak?fbclid=IwAR1E9PoBxuWURZRJlA4D0VrnESbfjGfC2xKuvVJzCRUmIJy7ZRKMkkH8I-U

```

And it generates a 404 on Discourse.

Is there a trick to getting Discourse to ignore the fbclid parameter?
