Comunica Fetch HTTP Actor
An HTTP actor that uses fetch to perform HTTP requests.
When this actor is used in Node.js, a memory-based cache will be initialized.
This cache is only used when the httpCache context flag is enabled.
This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
When this actor is used, a custom fetch implementation may be provided via the context (fetch).
If none is provided, the global fetch implementation from the runtime or a polyfill is used.
