Pull Request Overview

This PR updates how the request URL is derived by introducing a port-resolution logic that considers the "X-Forwarded-Host" and "Host" headers and updates the URL construction accordingly.

• Updated URL derivation logic to include port extraction
• Modified URL construction using the new port information
• Added tests to validate the correct parsing of the URL and port

The variable 'req' is used instead of the function parameter 'request'. Use 'request.get(...)' to maintain consistency with the function signature.

Suggested change

	// req.hostname doesn't include port information so grab that from
	// `X-Forwarded-Host` or `Host`
	let [, hostnamePortStr] = req.get("X-Forwarded-Host")?.split(":") ?? [];
	let [, hostPortStr] = req.get("host")?.split(":") ?? [];
	// request.hostname doesn't include port information so grab that from

	let [, hostnamePortStr] = request.get("X-Forwarded-Host")?.split(":") ?? [];
