Implementing the Idempotency-Key specification on Apache APISIX

Last week, I wrote an analysis of the IETF Idempotency-Key specification. The specification aims to avoid duplicated requests. In short, the idea is for the client to send a unique key along with the request:

• If the server doesn't know the key, it proceeds as usual and then stores the response
• If the server knows the key, it short-circuits any further processing and immediately returns the stored response

This post shows how to implement it with Apache APISIX.
