Yeah, I don't know about that. Wouldn't it be that the query strings differentiate the two links?

I assume so, because of an old trick where query strings are used for ad-hoc cache control as in /style.css?1629472765

You’re right, I wasn’t paying close enough attention. That’s what I get for reading HN mostly on my phone!

Query string is to differentiate the links (to understand which case is getting triggered)

OK, but then the prefetch link as it stands is useless, no?
