A system and a method for accelerating delivery of a webpage by using a preloader file during a delay in fetching the web file are disclosed. When an end user makes a request through a client computer for a webpage, a Content Delivery Network (CDN) server sends the client a preloader file. The preloader file contains requests for resources that are likely to be part of the web file. The client downloads the resources, and the resources are saved in a browser cache. The preloader file also directs the client to request the webpage again. While the client is downloading the resources, the CDN server requests the web file from an origin server. The origin server composes the webpage and delivers the webpage to the CDN server. When the client makes a second request for the web file, the CDN server delivers the web file to the client. When the client renders the web file to display the webpage, the client can retrieve the resources from the browser cache. |
