Go Idem Proxy

an HTTP proxy to get idempotency on POST requests

Run

go-idem-proxy --redis-url=redis:6379 --target-url=http://localhost:3000

• The proxy will expect an X-idem-token header (can be overriden with IDEM_TOKEN=myHeader env var) on every POST request

if it's not present :

• it will reject the request with a 400
• Otherwise, it will check if there's something at the key=<value_of_the_header> (in the Redis database)

If there's something:

• it will return the cached response without forwarding the request
• Otherwise, it will forward the request and store the response for later use.

NB : the default TTL is set at 60 seconds, you can override that with CACHE_TTL env var
