Hello,

i have some questions about digest authentication and in particular on the
way communication beetween squid, the client and the helper takes place
(I'm testing digest_pw_auth).

1. Who does create the challenge for the user? Squid or the helper?

2. In the case it is Squid, what does it pass to the helper on stdin?

3. And how does the helper reply? OK or ERR as usual?

4. What is intended for HHA1, since I can find no reference to it in
RFC2617? Maybe a different notation?

Thank you in advance.
