With Httpq, you can buffer HTTP requests and replay them later, and persistence can be either to Redis or to disk. This is useful for buffering HTTP requests that do not have to be processed in realtime, such as webhooks.
$ go install github.com/DavidHuie/httpq/cmd/httpq
$ httpq -redis=true -redis_url=":6379"
$ httpq -db_path="/tmp/httpq.db"
$ curl localhost:3000/push
$ curl localhost:3000/pop
GET /push HTTP/1.1
Host: localhost:3000
Accept: */*
User-Agent: curl/7.37.1
The result is returning as JSON.
$ curl localhost:3000/size
