【 摘 要 】

An e-transaction is a powerful abstraction that ensures exactly-once semantics in three-tier applications. It is very common for applications on the Internet to follow a three-tier architecture, and we discuss protocol and implementation issues for e- transactions in the Internet setting (so-called web e- transactions). In contrast to current related protocols, which require some sort of retry logic in the client-side software, our protocol assumes a standard web browser and only uses the semantics of HTML and HTTP to implement the required client-side retry logic. We discuss how to implement the server side of our protocol in the context of JAVA servlets. Notes: Copyright CSREA. Published in Internet Computing, Las Vegas, NV, June 25-28, 2001. 9 Pages
