AJAX ASP
An existing ASP endpoint can be called through HTTP just like another data source. Keep legacy server details behind a clear JSON contract.
Where to run this
Use a local browser project for this example. It needs browser permissions, additional files, a server endpoint, or a library as described below. The restricted playground cannot provide those dependencies.
A practical example
const response = await fetch("/api/sessions.asp");
if (!response.ok) throw new Error("Request failed");
console.log(await response.json());
What happens
A working ASP server can return a JSON response for the client.
