Just a couple of potential issues:
Digest and to a lesser extent NTLM authentication will _need_ a shared
credential cache. Digest potentially changes the challenge on every
request-response pair, so all frontend processes will need the same
challenge status information. NTLM challenge-auth caching will lose most of
it's benefits if we push it back out to the helpers - we then have to do two
round trips to the helper for every client connection.
