问题


I have started to load a few key resources and pages using the prefetch/prerender system.

Is there a way to ensure that the resources in question are actually being preloaded?


回答1:


Google recommends using the Page Visibility API to test if a page is being prerendered. I'm not sure how well it works cross-browser (but what does in HTML5).




回答2:


You can also use prerender-test.appspot.com to test that your site works correctly under prerendering. Further, from within Chrome, you can go to chrome://net-internals#prerender to see a list of attempted prerenders and whether they were used, and if they were not used, why they were canceled.
