Proxy and .pac interaction

[martinthomson]

Ryan asks what you should pass to proxy.pac when you know about a potential alt-svc.

I suggested that you use the original request origin and only use alternatives if the proxy.pac doesn't provide a proxy address. That is proxy.pac overrides alternative services.

[mnot]

Yeah. Alt-Sv is for finding an origin, not for finding a proxy -- a proxy might use it, though.

This should all be clear based upon reading of RFC7230, but if not we could add a sentence or two to clarify.

Is there something we need to do here?

[RolandZink]

Maybe we need to specify an alternative to pac files or define how to
get a proxy for http over TLS in pac.

For this spec, I think we could just add a sentence to the effect that 'clients configured to use a proxy SHOULD NOT use alternative services."

[mnot]

Add: "A client configured to use a proxy for a given request SHOULD NOT send it to an alternative service, but instead use that proxy."

[mnot]

Modification: "A client configured to use a proxy for a given request SHOULD NOT directly connect to an alternative service for it, but instead route it through that proxy."

(seems the discussion on the mailing list hasn't come to a conclusion)

[mnot]

It did regarding this issue, I think; the remaining discussion is a tangent.
