   org.apache.commons.httpclient.auth.AuthPolicy

AuthPolicy
abstract public class AuthPolicy (Code)
Authentication policy class. The Authentication policy provides corresponding authentication scheme interfrace for a given type of authorization challenge.

The following specifications are provided:

  • Basic: Basic authentication scheme as defined in RFC2617 (considered inherently insecure, but most widely supported)
  • Digest: Digest authentication scheme as defined in RFC2617
  • NTLM: The NTLM scheme is a proprietary Microsoft Windows Authentication protocol (considered to be the most secure among currently supported authentication schemes)

   $Revision: 480424 $
since:
   3.0


Field Summary
final public static  StringAUTH_SCHEME_PRIORITY
     The key used to look up the list of IDs of supported AuthScheme authentication schemes in their order of preference.
final public static  StringBASIC
    
final public static  StringDIGEST
     Digest authentication scheme as defined in RFC2617.
final protected static  LogLOG
     Log object.
final public static  StringNTLM
     The NTLM scheme is a proprietary Microsoft Windows Authentication protocol (considered to be the most secure among currently supported authentication schemes).


Method Summary
public static synchronized  AuthSchemegetAuthScheme(String id)
     Gets the AuthScheme authentication scheme with the given ID.
public static synchronized  ListgetDefaultAuthPrefs()
     Returns a list containing all registered AuthScheme authentication schemes in their default order.
public static synchronized  voidregisterAuthScheme(String id, Class clazz)
     Registers a class implementing an AuthScheme authentication scheme with the given identifier.
public static synchronized  voidunregisterAuthScheme(String id)
     Unregisters the class implementing an AuthScheme authentication scheme with the given ID.

Field Detail
AUTH_SCHEME_PRIORITY
final public static String AUTH_SCHEME_PRIORITY(Code)
The key used to look up the list of IDs of supported AuthScheme authentication schemes in their order of preference. The scheme IDs are stored in a java.util.Collection as java.lang.String s.

If several schemes are returned in the WWW-Authenticate or Proxy-Authenticate header, this parameter defines which AuthScheme authentication schemes takes precedence over others. The first item in the collection represents the most preferred AuthScheme authentication scheme , the last item represents the ID of the least preferred one.

BASIC
final public static String BASIC(Code)
Basic authentication scheme as defined in RFC2617 (considered inherently insecure, but most widely supported)



DIGEST
final public static String DIGEST(Code)
Digest authentication scheme as defined in RFC2617.



LOG
final protected static Log LOG(Code)
Log object.



NTLM
final public static String NTLM(Code)
The NTLM scheme is a proprietary Microsoft Windows Authentication protocol (considered to be the most secure among currently supported authentication schemes).





Method Detail
getAuthScheme
public static synchronized AuthScheme getAuthScheme(String id) throws IllegalStateException(Code)
Gets the AuthScheme authentication scheme with the given ID.
Parameters:
  id - the AuthScheme authentication scheme ID AuthScheme authentication scheme
throws:
  IllegalStateException - if a scheme with the ID cannot be found



getDefaultAuthPrefs
public static synchronized List getDefaultAuthPrefs()(Code)
Returns a list containing all registered AuthScheme authentication schemes in their default order. AuthScheme authentication scheme



registerAuthScheme
public static synchronized void registerAuthScheme(String id, Class clazz)(Code)
Registers a class implementing an AuthScheme 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 AuthScheme authentication scheme from AuthPolicy.getAuthScheme(String) .

Please note that custom authentication preferences, if used, need to be updated accordingly for the new AuthScheme authentication scheme to take effect.


Parameters:
  id - the identifier for this scheme
Parameters:
  clazz - the class to register

unregisterAuthScheme
public static synchronized void unregisterAuthScheme(String id)(Code)
Unregisters the class implementing an AuthScheme authentication scheme with the given ID.
Parameters:
  id - the ID of the class to unregister
