Lack of mechanisms to control and communicate with them brings about scalability issues with intermediaries themselves, and lack of strong, scalable coherence mechanisms limits their adoption by both end users and content publishers. Furthermore, access providers who wish to provision caching proxies in their networks have no standardized mechanism to announce such devices to user agents. It is expected that after requirements for intermediary discovery and description are gathered and evaluated, the working group will re-charter to continue that work. Issues pertaining to coordination between multiple administrative domains are explicitly out of scope in this group's work items.
Work associated with the modification of messages by intermediaries is also out of scope.
