COMPUTER NETWORKING SYSTEM AND METHOD WITH JAVASCRIPT EXECUTION FOR PRE-FETCHING CONTENT FROM DYNAMICALLY-GENERATED URL AND JAVASCRIPT INJECTION TO MODIFY DATE OR RANDOM NUMBER CALCULATION

An apparatus, method, and non-transitory computer-readable medium comprising program code which when executed by an apparatus causes the apparatus to effect the method, for pre-fetching web content. Preferably, a proxy server performs the pre-fetching. Techniques such, for example, as executing Javascript in pre-fetched pages, modifying pre-fetched pages to address URL generation involving random numbers or dates, using cookie information or browser specifics when performing pre-fetching of pages, and injecting Javascript to measure response time may be performed, by way of example.
