Description:

I'm using Ky to make calls to the Matrix API. Whenever I receive a rate-limited error with status code 429 I'm forced to parse the body of the error in order to retrieve the value for retry_after_ms before doing the next request.

Ky has a built in retry mechanism and honors the http header Retry-After that represents either an absolute date/time or a delay in seconds.

Can you please add the appropriate http header to 429 errors? I'm using Synapse v1.82 in a dockerized setup.

Thanks,
Thomas
