A computing system used for graphical user interface image reproduction includes a processor; and a memory communicatively coupled to the processor. The processor is configured to: extract data from network traffic being sent from a server to a first client device, the network traffic including cacheable files used to create a graphical user interface display on the first client device; store the cacheable file in a trace file associated with the first client device; and send the cacheable file to a second client device in response to a request from the second client device.
