Exploring Transition-Based Services at the 49th IETF BOF in San Diego

The 49th IETF BOF, chaired by Michael Condry and Hilarie Orman, convened to discuss advancements in web caching and the introduction of transit-based services for intermediaries. Key discussions included application-specific services and the evolution of the client/server model. The workshop, held on September 13, 2000, aimed to establish a charter, understand draft relationships, and solicit design team members. The agenda featured presentations on use cases, ICAP progress, and document roadmaps, culminating in a collaborative effort to shape the future of proxy services.
