Session: A Nice To Have

Every e-commerce application must support session tracking. Unfortunately, MIDP (Mobile Information Device Profile), a J2ME (Java 2 Platform, Micro Edition) technology, supports only the standard HTTP protocol, which is stateless.

They discuss the implementations, usages, and relative merits of three approaches: using cookies, rewriting URLs, and embedding session information in XML documents.
