Explainer No information provided Specification https://github.com/whatwg/html/pull/11765 Summary Prevents an ongoing navigation from being unnecessarily canceled by a new, identical navigation that is initiated in quick succession. This optimization improves performance and the user experience by not wasting resources on a duplicate request, which can be caused by accidental double-clicks. Blink component UI>Browser>Navigation Web Feature ID Missing feature Motivation We observe users sometimes navigate to the same URL in quick succession, likely by accident. Because new navigations take precedent over an older one, this means it will waste the earlier navigation that's already in progress, potentially wasting a response that is already in flight for the navigation and causing the user to wait longer (from the time the first navigation kicks off). To mitigate this waste, the feature will ignore the duplicate navigation and let the first navigation continue. Initial public proposal https://github.com/whatwg/html/issues/11743 TAG review https://github.com/w3ctag/design-reviews/issues/1240 TAG review status Issues open Goals for experimentation We have already conducted experimentation which showed positive results in reducing duplicate queries sent to servers. Risks Interoperability and Compatibility The user-facing behavior will remain identical, as we only target duplicate navigations under specific conditions, such as same URLs and close start times. One minor change to web-exposed behavior is that the initial navigation is now maintained instead of being replaced by the subsequent duplicate request. Gecko: No signal (https://github.com/mozilla/standards-positions/issues/1307) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/563) Web developers: No signals Other signals: Ergonomics N/A Activation N/A Security The feature prevents cross-site leak risks by ensuring that an initiator document cannot detect or infer cookie changes made by other documents. No cross-site state information is ever exposed during the duplicate navigation check. WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? To minimize compatibility risks, navigation callbacks and history entries preserve their legacy behavior, preventing application breakage. Debuggability N/A Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes We are currently rolling out this feature on WebView. On other platforms, the experiment has already concluded and we are shipping it. Is this feature fully tested by web-platform-tests? No Flag name on about://flags No information provided Finch feature name IgnoreDuplicateNavs Rollout plan Will ship enabled for all users Requires code in //chrome? False Tracking bug https://crbug.com/366060351 Launch bug https://launch.corp.google.com/launch/4428715 Availability expectation Feature is available only in Chromium browsers. It is not clear if/when other browsers will follow. Adoption expectation Feature is considered a best practice for some use case within 12 months of reaching Web Platform baseline. Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? No. Estimated milestones Shipping on desktop 151 Shipping on Android 151 Shipping on iOS 151 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way). Standard criteria for duplicate navigations are being finalized within the WHATWG HTML specification.
