Because the browser may preemptively send auth info, incrementing the * nonce-count when it does, and because the client does not get notified * if the URI didn't need authentication after all, we need to be sure to * update the nonce-count each time we receive an Authorization header no * matter what the final outcome of the request. Furthermore this is a * convenient place to get the reques

 * r->proxyreq is set correctly.
