DNS caching?

[jwodder]

What is the nature of httpx's DNS caching, if any? I'm currently working with a script that creates multiple concurrent AsyncClients connecting to the same server, and I'm running into DNS errors (specifically, socket.gaierror, "Nodename nor servname provided or not known") that go away when the number of concurrent clients is heavily limited. The ability to cache DNS lookups at a super-client level in order to avoid this problem would be helpful.

The package does not currently provide any DNS caching.

For comparison with other similar package, aiohttp does, but requests does not.

Agree that it's probably worthwhile for us to have on the roadmap. I'd be happy for someone to open an issue to request it as a feature.
