Response.useFinalURL
Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
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.
