java.lang.Objectorg.apache.commons.httpclient.auth.AuthPolicy
public abstract class AuthPolicy
Authentication policy class. The Authentication policy provides corresponding authentication scheme interfrace for a given type of authorization challenge.
The following specifications are provided:
| Field Summary | |
|---|---|
static String |
AUTH_SCHEME_PRIORITY
The key used to look up the list of IDs of supported authentication schemes in their order of preference. |
static String |
BASIC
Basic authentication scheme as defined in RFC2617 (considered inherently insecure, but most widely supported) |
static String |
DIGEST
Digest authentication scheme as defined in RFC2617. |
protected static Log |
LOG
Log object. |
static String |
NTLM
The NTLM scheme is a proprietary Microsoft Windows Authentication protocol (considered to be the most secure among currently supported authentication schemes). |

public static final String AUTH_SCHEME_PRIORITY
authentication schemes in their order of preference. The scheme IDs are
stored in a Collection as Strings.
If several schemes are returned in the WWW-Authenticate
or Proxy-Authenticate header, this parameter defines which
authentication schemes takes precedence over others.
The first item in the collection represents the most preferred
authentication scheme, the last item represents the ID
of the least preferred one.

public static void registerAuthScheme(String id,
Class clazz)
authentication scheme with
the given identifier. If a class with the given ID already exists it will be overridden.
This ID is the same one used to retrieve the authentication scheme
from getAuthScheme(String).
Please note that custom authentication preferences, if used, need to be updated accordingly
for the new authentication scheme to take effect.
