Re: Http authentication

I understand that the very first request shouldn't contain any auth header.
But If a svn function is called multiple times(for the same host etc.) and
there was already a successful authentication, it should be possible to add
the auth header to the following requests instead of waiting for a auth
required response. At least I hoped so.
