I'm wondering would the network request be successful if a 302 redirect is placed on the server and the app doesn't explicitly implement 'willPerformHTTPRedirection' delegate?
We are working on domain migrations and are concerned about backward compatibility of apps to make successful requests(200) when the url redirects are effective.
Appreciate the help.
URLSession will automatically follow redirects. You can use the ‘will perform HTTP redirection’ delegate method to override that default behaviour , but the default is to follow redirects.

 In standard sessions; this delegate isn’t called in background sessions.
