In this work we present a protocol ensuring the e-Transaction guarantee (i.e. a recently proposed end-to-end reliability guarantee) in a Web based, three-tier transactional system. The protocol does not need any coordination among the replicas of the application server, thus exhibiting negligible overhead in normal behavior. Additionally, it achieves highly efficient fail-over especially for the case of back-end database employing Optimistic Concurrency Control (OCC), namely a type of concurrency control well suited for data access performed via Web. We also present a comparative discussion with existing solutions and a quantitative analysis of the proposed protocol, which clearly quantifies its benefits, in terms of reduced user perceived latency, especially when employed in combination with OCC.
