Encoding here is interpreted very simply. Parts are encoded with no
punctuation after them and parameters are comma separated with the value in
quotes. This means that for basic authentication, part 1 must be 'Basic' and
part 2 is the credentials. For digest, part1 is 'Digest', and the
digest-response is stored in parameters.
