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.

Warning: This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the PerformanceNavigationTiming interface instead.
The legacy PerformanceTiming.redirectEnd read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, the last HTTP redirect is completed, that is when the last byte of the HTTP response has been received. If there is no redirect, or if one of the redirect is not of the same origin, the value returned is 0.
