Examples of WwwAuthenticateHeader

javax.sip.header.WWWAuthenticateHeader

This interface represents the WWW-Authenticate response-header. A WWW-Authenticate header field value contains an authentication challenge. When a UAS receives a request from a UAC, the UAS MAY authenticate the originator before the request is processed. If no credentials (in the Authorization header field) are provided in the request, the UAS can challenge the originator to provide credentials by rejecting the request with a 401 (Unauthorized) status code. The WWW-Authenticate response-header field MUST be included in 401 (Unauthorized) response messages. The field value consists of at least one challenge that indicates the authentication scheme(s) and parameters applicable to the realm.

For Example:
WWW-Authenticate: Digest realm="atlanta.com", domain="sip:boxesbybob.com", qop="auth", nonce="f84f1cec41e6cbe5aea9c8e88d359", opaque="", stale=FALSE, algorithm=MD5 @see Parameters @author BEA Systems, NIST @version 1.2
