Motivation

Currently, the handle_http_requests doesn't allow us to return an error when handling requests. This can be solved by handling them via a map_requests function like in handle_authrpc_requests. While handle_authrpc_requests handles comunication between clients and handle_http_requests handles comunication between the client and users, there are a lot of requests that are handled by both of them. As they both use the same request format, there is little reason to implement two different functions to handle the same requests in the same way. We can use map_requests to handle both auth_rpc and http requests, and then implement a second handler (such as map_internal_requests) to handle auth_prc-specific requests.

Description

Replaces handle_http_requests request handling with a call to map_requests
