domainLookupStart property

int get domainLookupStart

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

The legacy PerformanceTiming.domainLookupStart read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, where the domain lookup starts. If a persistent connection is used, or the information is stored in a cache or a local resource, the value will be the same as PerformanceTiming.fetchStart.

Implementation

external int get domainLookupStart;
