Ticket #179 (closed design: fixed)
Relax Via MUST

Currently, intermediaries MUST add the Via header;
The Via general-header field MUST be used by gateways and proxies to indicate the intermediate protocols and recipients between the user agent and the server on requests, and between the origin server and the client on responses.
This doesn't reflect current practice.
When making this decision, it's worth noting that some HTTP mechanisms operate differently when a message sender knows that the entire path is HTTP/1.1, and the primary way of discovering this is the Via header.
