Multiple slashes in URL.

[Annuksun]

Hi All,

My website's started experiencing a weird issue with URLs recently. In Google Search Console I see URLs with multiple slashes at the end. For ex.

https://www.mydomain.com/collections/henne-organics?order=bestseller///////////

Obviously, they create a potential danger of duplicate content. Tried all sorts of information but cannot find anything about it. Has anyone experienced the same? How to fight it? Any thoughts?

I've already added a correct canonical for such URLs so the example above will be pointing at https://www.mydomain.com/collections/henne-organics but I'm not sure it's enough. It would be great to get an understanding of why it's happening in the first instance. It may be just a tip of the iceberg that I don't see yet. 

Any ideas are much appreciated!

Thanks!
