Abstract
On an embedded device with a web server, pages are marked as having non-cacheable HTML portions and cacheable graphics portions. Marking the HTML portion as non-cacheable allows for the retrieval of a web page containing the latest status information without retrieving the graphics images. A refresh function is provided that allows for the comparing of non-cached portion time stamps with the stamps of the page on the web server. When the time stamp of the page on the web server is more current than the time stamp of the non-cached portion, the non-cacheable portion of the web page is retrieved from the web server. Retrieving the non-cacheable HTML portion from the web site without retrieving the cached portion reduces the amount of time needed to refresh the display image. A timer may be employed to refresh the web page at predetermined intervals, while using the current URL or the history list of the browser to reach the desired web site and retrieve the current status of the embedded device. The refresh function may be activated by a button available on the browser or by a refresh button on the web page.
