p1 Section 2.3 says:

> However, an HTTP-to-HTTP gateway that wishes to interoperate with third-party HTTP servers must conform to HTTP user agent requirements on the gateway's inbound connection and must implement the Connection (Section 6.1) and Via (Section 5.7.1) header fields for both connections.

This means that accelerators and CDNs MUST generate a Via header on the outbound connection. This isn't widely practiced, and I'm not sure it's necessary. Comments?
