How to create an HTTP Proxy?
Which library / approach would be advisable for building an MITM-style HTTP(s) Proxy, i.e. for intercepting outgoing web traffic? Effectively inspect (and do side effects) based on outgoing traffic.
I found GitHub - houli/http-proxy: A HTTP(S) Proxy written in Elixir · GitHub (9 years old, work in progress) and GitHub - KazuCocoa/http_proxy: http proxy with Elixir. wait request with multi port and forward to each URIs · GitHub, but there’s no real getting-started sample. Given that a proxy isn’t just a regular web server, I’m not sure this thing can easily be plugged into a web server like Cowboy/Bandit/Phoenix…
Thanks, Christian

How so? The requirements may widely wary, however I can see how you could have a combination of phoenix and a http client.

It sounds like you’re looking for an http server that supports the CONNECT protocol, such as the standalone app squid.
I haven’t personally seen any Erlang or Elixir http servers that have explicit documented support of HTTP CONNECT for proxying, but cowboy does appear to support enable_connect_protocol for Websockets on HTTP2. Might take a bit of experimentation with cowboy’s configuration to determine if it suits your need.
