// http:// uris through a proxy will all share the same CI, because they can
// all use the same connection. (modulo pb and anonymous flags). They just use
// the proxy as the origin host name.
// however, https:// uris tunnel through the proxy so they will have different
// CIs - the CI reflects both the proxy and the origin.
// however, proxy conenctions made with http/2 (or spdy) can tunnel to the
// origin and multiplex non tunneled transactions at the same time, so they have
// a special wildcard CI that accepts all origins through that proxy.
