Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The useFinalURL
property of the Response
interface contains a boolean stating whether this is the final URL of the response.
This property applies only to ServiceWorkers. In other contexts it will return undefined
.
Syntax
var isfinalURL = Response.useFinalURL;
Value
A Boolean
indicating whether or not the URL is final rather than a redirect.
Example
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.
