Hi, does the Ktor client have a built-in way of automatically delaying/pausing then retrying when it receives a 429 response? Is there a plugin that could do that for me?

Ktor 2.0 has I believe a new

HttpRequestRetry

feature....not sure though how much it's behaviour can be customized

You can find more information about this plugin in the documentation.

Thanks. I'm specifically looking for something I could use in production (so excluding 2.0 stuff for now), and I don't think HttpRequestRetry is able to use the response from 429 to adapt its wait time, can it?

HttpRequestRetry

will support

Retry-After

header by default
