This directory contains an example component implementing a simple "passthrough cache" service responsible for fetching the content bytes of a given URL from a supplied origin service.
The component imports two interfaces: a cache implementation for storing previously fetched content and an "origin" backend implementation for forwarding the request to when there is a cache miss.
It exports the same backend interface as it imports, effectively wrapping the provided import interface with some simplistic caching logic.
To build the component, run the following command:
cargo component build
The component should now exist at target/wasm32-wasip1/debug/service.wasm.
