XMLHttpRequest: responseURL property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since August 2016.

Note: This feature is available in Web Workers, except for Service Workers.

The read-only XMLHttpRequest.responseURL property returns the serialized URL of the response or the empty string if the URL is null. If the URL is returned, any URL fragment present in the URL will be stripped away. The value of responseURL will be the final URL obtained after any redirects.

Example

js
const xhr = new XMLHttpRequest();
xhr.open("GET", "http://example.com/test", true);
xhr.onload = () => {
  console.log(xhr.responseURL); // http://example.com/test
};
xhr.send(null);
