To verify the functioning of the prerender you can use the Google Chrome task manager. The following image shows an example page that includes the Prerender link tag in the HTML head. When it finishes loading the example page, Chrome also loads the page indicated in the prerender, the activity is visible in the task manager under the "Activity" item with the name "Prerender". If you see the prerender activity in the Chrome task manager you are sure that you have implemenated the function well. Test Prerender with Chrome Task Manager Test Prerender with Chrome Task Manager Differences between Preload and Preconnect, dns-prefetch, prefetch and prerender In this blog I have described several useful techniques for anticipating the loading of critical resources in the browser via the HTTP header or meta tag: Preloading requires you to download dependencies, such as JS, CSS, and fonts. Preloading is best suited for resources normally discovered late by the browser, such as in critical chain requests.
By preloading a certain resource, you are telling the browser that you would like to Hong Kong Phone Number fetch it sooner than the browser would otherwise discover it because you are certain that it is important to the current page. The Preconnect and dns-prefetch require you to start establishing a connection with the remote server. You can speed up load time by 100–500 ms by establishing early connections to important third-party sources. These numbers may seem small, but they make a difference in how users perceive web page performance. Prefetch tells the browser a resource to download as soon as the active page has finished loading. When the browser encounters the tag it will begin to request the resource(s) such as an image or HTML page. Prefetch allows you to download individual resources such as images, HTML pages, style sheets, etc.
The impact of Prefetch on page loading speed therefore depends on which resource is pre-loaded. Prerender is the only option that cannot be transmitted via HTTP header. The prerender asks the browser to start rendering a new page. Prerendering is the most powerful of the technologies presented here, but it also carries the greatest risks. It essentially ensures that a URL with all the necessary static resources is fully loaded and set in the background. HTTP/2 Server Push is a feature that allows a server to preemptively push resources to the client (without a corresponding request).
