class digest_auth_handler :?enable_auth_in_advance:bool -> #key_handler ->
auth_handler
This handler is compatible with RFC 2069 and RFC 2617. In particular, the following protocol options are available:
Authentication-Info
header is completely
ignoredenable_auth_in_advance
: If set to true
, authentication can be
done in advance, i.e. before the server requests authentication.
This reduces the number of messages exchanged with the server, but
may be an additional security risk.
