*Specification* https://github.com/explainers-by-googlers/prefetch-activation-beacon *Summary* The on-prefetch-activation HTTP response header enables servers to specify a telemetry endpoint that the browser notifies when a prefetched resource is used for navigation. Developers gain a reliable signal to measure the precision and performance impact of their prefetch strategies. *Blink component* Blink>Loader>Preload <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ELoader%3EPreload%22> *Web Feature ID* Missing feature *TAG review* *No information provided* *TAG review status* Pending *Goals for experimentation* We are going to start origin trial for the prefetch activation beacon to evaluate whether it can reliably report all the user navigation when the page is prefetched. We will compare the DAU and the query count with a group not using the API and reports activation via javascript. *Origin Trial documentation link* https://github.com/explainers-by-googlers/prefetch-activation-beacon *Risks* *Interoperability and Compatibility* *No information provided* *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: *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? No *Ongoing technical constraints* None *Debuggability* Basic support, the activation beacon request will be shown in the devtools network panel. *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* Yes *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* Yes *Flag name on about://flags* prefetch-activation-beacon *Finch feature name* PrefetchActivationBeacon *Non-finch justification* *No information provided* *Requires code in //chrome?* False *Tracking bug* https://b.corp.google.com/issues/499814382 *Launch bug* https://launch.corp.google.com/launch/4468679 *Estimated milestones* Origin trial desktop first 151 Origin trial desktop last 155 Origin trial Android first 151 Origin trial Android last 155 Origin trial WebView first 151 Origin trial WebView last 156 *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5118934710878208?gate=5919970639872000 *Links to previous Intent discussions* Intent to Prototype: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/CAJQw1NzrnJBU7pmpz7bfxK2G7cWUcJsaU9ekFHh3XKFUyzzrwg%40mail.gmail.com This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
