(1) (Internet Content Adaptation Protocol) A high-level protocol for requesting services from an Internet-based server. iCAP provides a common format for requesting services using standard HTTP messaging. It provides a remote procedure call (RPC) capability, allowing iCAP clients to invoke services on iCAP servers for a variety of services, including ad insertion, virus scanning and foreign language translation. iCAP is expected to provide the interoperability so that value-added services can "plug and play" on the Internet.
