Abstract
The increasing popularity of heterogeneous Webenableddevices and wired/wireless connections motivatesthe diffusion of content adaptation services that enrich thetraditional Web. Different solutions have been proposedfor the deployment of efcient adaptation and delivery services:in this paper we focus on intermediate infrastructuresthat consist of multiple server nodes. We investigatewhen it is really convenient to place this distributed infrastructurecloser to the clients or to the origin servers,and which is the real gain that can be get by node cooperation.We evaluate the system performance through threeprototypes that are placed in a WAN-emulated environmentand are subject to two types of workload.
