This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the PerformanceNavigationTiming interface instead.

The legacy PerformanceTiming.redirectStart read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, the first HTTP redirect starts. If there is no redirect, or if one of the redirect is not of the same origin, the value returned is 0.


time = performanceTiming.redirectStart;
