Detect origin for urls of different forms

[inc-osaulenko]

Currently, origin is detected by taking the part of URL prior to /oauth2/ and for URLs like this

https://www.domain.com/oauth2/{some-client-id}

It works as expected. However, when the service that uses OKTA API is behind a multi-tenant proxy and URL will be like

https://www.domain.com/{lang}/{tenant-id}/oauth2/{some-client-id}

It doesn't work. There is an option to do the same thing using (new URL('...')).origin but that will require to add another polyfill for IE11. This one uses Array.prototype.split which is available in IE11 and requires no polyfill.

Hi team,

It’s been nearly two years since this feature request was accepted for review, but there haven’t been any updates. Can you please provide an update on its status and whether it is still being considered for implementation?

This functionality is important for our mutual customers, and the lack of visibility makes planning difficult.

Any guidance would be appreciated.
