developerWorks : Web services : A Primer for HTTPR

The delivery of messages using a reliable transport mechanism is a fundamental component for middleware in e-business systems, and a needed technology in enterprise computing. However, in the wider context of the Internet, synchronous transport protocols such as HTTP do not currently provide those facilities. Reliable HTTP (HTTPR) addresses these deficiencies by proposing rules that make it possible to ensure that all messages are delivered to their destination in their exact form and only once. In cases where the message delivery fails, the protocol will reliably report the message as undeliverable.
