Retry-After
In the case of certain errors, this header specifies a length of time after which the client can re-try the request.
Writing responses (origin servers)
If the server enforces request limits, specify the soonest time after which the client using those credentials will be able to make a successful request.
This header should be used with the 429 (Too Many Requests) status code.
Reading responses (user agents)
The header implies that the same request may be successful if retried later; wait at least the specified number of seconds before trying this.
