URL Prefetching

Abstract

An enhanced tag management system is disclosed comprising a networked resource/asset prefetch feature. In some examples, the tag management system comprises a recommendation system, a collection system, a non-volatile data store, a user computing device with cache memory, and/or other components. The enhanced tag management system permits prefetching of resource/assets, such as images, videos, widgets, etc., while avoiding the skewing of analytical results. As a result, a user computing device may enjoy enhanced performance and reduced latency without sacrificing the reliability of collected analytics data.

We claim: 
     
         1 . A method comprising:
 receiving, at a user terminal from a server computer, first program instructions configured to regulate execution of analytics tags at the user terminal, including asynchronous execution of the analytics tags at the user terminal;   receiving from the server computer, in response to a request sent by the first program instructions executing on the user terminal to the server computer, analytics tags configured to execute at the user terminal, wherein the analytics tags are associated with a first web page;   determining, at the server computer, a second web page linked from the first web page;   determining, at the server computer, a third web page linked from the first web page;   after receiving notification of completion of loading of the first web page, downloading, at the user terminal, one or more analytics tags corresponding to the second web page and one or more analytics tags corresponding to the third web page;   bypassing execution, by the first program instructions, of the downloaded analytics tags of the second web page and the third web page;   storing the downloaded analytics tags of the second web page and the third web page in a cache memory at the user terminal; and   in response to accessing one of the second web page and the third web page, providing, from the cache memory, one or more tags of the stored analytics tags instead of downloading again the one or more tags of the stored analytics tags.
