Support for the new RateLimit standardization proposal

[ioggstream]

I wish

this framework(eg. eventually via configuration) the new ratelimit standardization proposal.

The proposal was:

• presented at the HTTP Workgroup during the IETF Meeting
• implemented by Kong, Envoy Proxy and 3scale API gateway

The proposal

Very similar to your current implementation, but header names have no X- and Reset is in delta-seconds instead of timestamp. The rationale for the choice is in FAQ 5.

RateLimit-Limit: 60
RateLimit-Remaining: 50
RateLimit-Reset: 5

Proposed change

The line to be changed (even via a configuration parameter) is to return "X-RateLimit-Reset" with the same value as Retry-After.

Notes

Your feedback on the ratelimit spec is very welcome!
