The record
Alice exposes a Python SDK `ProxyShare` with a fixed target URL. Bob sends a request to the share with an absolute URL in the path. The Flask handler passes that path to `urllib.parse.urljoin`, which replaces Alice's configured target host with Bob's host and returns the server-side response to Bob.
