Library to Forward HTTP Requests


This library provides a plugin to proxy http requests.

API

Configuration is managed by a dedicated CA per user (e.g., admin), using a SharedMap with a well known name (e.g., forwarding) to store the routing table.

Bindings in that table are of the form caName -> new_url_prefix, where caName is the first element of the original url path (respecting - syntax).

For example, if we are accessing a resource https://root-xx.cafjs.com/foo-ca1/xx.md, we use the SharedMap forwarding of CA foo-admin in the application root-xx. If it contains the binding:

foo-ca1 -> https://somewhere.com

then we rewrite the address to https://somewhere.com/xx.md before we forward the HTTP request.
