Abstract:
1. A method for reducing the latency involved in retrieving a web page, comprising: receiving a request from a browser to retrieve a target web page, wherein the request is received at a proxy server positioned between a high-latency satellite connection and a low-latency Internet connection, wherein the proxy server retrieves the target web page with low latency; forwarding the request to a host server; receiving components comprising the target web page at the proxy server; generating a graphical image of the target web page as a substitute web page, wherein the substitute web page includes the graphical image and a corresponding image map that assigns certain regions of the graphical image to corresponding hyperlinks, and wherein generating the graphical image involves assembling the target web page from the received components in a virtual terminal environment; and transferring the entire substitute web page to the browser in a single transfer across the high-latency satellite connection; wherein transferring the substitute web page involves only a single round-trip delay between the user browser and the proxy server, instead of multiple round-trip delays in transferring all the components individually in the actual target web page, thereby reducing the latency of web page loading at the user browser over the high-latency satellite connection to the Internet.
