Warning: This property has been removed from the spec. Do not attempt to use in your code.
The useFinalURL property of the Response interface contains a boolean stating whether this is the final URL of the response.
Note: This property applies only to ServiceWorkers. In other contexts it will return undefined.
SyntaxEdit
var finalURL = response.useFinalURL;
Value
A Boolean.
ExampleEdit
Consider a script residing in page index.html:
fetch('/test').then((r) => console.log(r.url))test.html is being controlled by the service worker sw.js:
onfetch = (e) => {
e.respondWith(fetch('/page2').then((r) => {
r.usefinalURL = true;
return r;
})
}The output will be /page2 and not /test in index.html, since setting the usefinalURL means that the response's URL is not set to request's URL.
