Forwarding starlette / ASGI requests as a reverse proxy

[couling]

I'm working through a POC for something and I'm investigating the possibility of using HTTPX as part of what effectively amounts to a reverse proxy. IE an ASGI / Starlette web app that has route which will recieve requests and forward them onto other microservives.

I wanted to know if httpx has anything that can aid transforming http requests from starlette (or raw ASGI) into httpx requests and visa versa with responses. I'm aware there could be quite a lot of complexity with this including chunked request / response bodies and http trailers to name just to edge cases.

Have I missed anything in httpx or supporting libraries that might help interpreting and forwarding ASGI requests?
