You are right :-)
I had never looked at the HTTP RFC myself, but assumed that the digest
method was flawed after reading some documentation about mod_auth_digest
in the distant past. I had read about APOP authentication a long time ago
after seeing the cucipop output from crosswinds.net's POP server, back in
the days.

I still have to read about DIGEST-MD5 in detail. I had suggested
CRAM/APOP as compared to plain password digests.

Thanks :-)
