Detailed Description

Parameters for digest-challenge.

The digest-challenge is sent by server or proxy to client. It can be included in, e.g, WWW-Authenticate or Proxy-Authenticate headers.

challenge        =  "Digest" digest-challenge
digest-challenge  = 1#( realm | [domain] | nonce |
                        [opaque] | [stale] | [algorithm] |
                        [qop-options] | [auth-param] )
domain            = "domain" "=" <"> URI ( 1*SP URI ) <">
URI               = absoluteURI | abs_path
nonce             = "nonce" "=" nonce-value
nonce-value       = quoted-string
opaque            = "opaque" "=" quoted-string
stale             = "stale" "=" ( "true" | "false" )
