Abstract This thesis documents the development of a optimization method that improves the user perceived performance of browsing the web on a device connected to the internet using a data network with low throughput and high latency. This is done by developing a new protocol, called CS-HTTP. The protocol allows that the content to be transferred can be compressed using both a specialized form of delta compression and general lossless compression. To better utilize the available throughput of the used data network the protocol supports pipelining of requests and that responses can be returned in any order. To measure improvement in user perceived performance a test framework is implemented. This test framework allows comparable and reproducible tests of different alterations to a system consisting of a user-agent simulator, originserver simulator and, if needed, a gateway-server simulator. Using the test framework it is shown that the optimization method developed offers significantly reduced transfer time and data transfer, thereby clearly improving the user perceived performance.
