What I'm finding is that when I make a few requests to various URLs on the same domain multiple DNS requests are made for the same domain. Once the first DNS response returned its cached I don't see any more requests for that domain - as expected.

The problem is, if I make enough requests to the same domain before the first DNS response returns, I can my client banned by the DNS server if I make too many requests.

Is there any way to de-duplicate concurrent requests for the same DNS address?

Thanks!

I've added this idea to the TODO now as something we want to get added, as we don't yet support this.
