Member Function Documentation

static void PHTTPAuthority::DecodeBasicAuthority ( const PString &  authInfo, PString &  username, PString &  password  )

staticprotected

Parameters

authInfo	Authority information string.
username	User name decoded from authInfo
password	Password decoded from authInfo

virtual PString PHTTPAuthority::GetRealm ( const PHTTPRequest &  request ) const

pure virtual

Get the realm or name space for the user authorisation name and password as required by the basic authorisation system of HTTP/1.0.

Returns

String for the authorisation realm name.

Parameters

request

Request information.

Implemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.

virtual PBoolean PHTTPAuthority::IsActive ( ) const

virtual

Determine if the authorisation is to be applied.

This could be used to distinguish between net requiring authorisation and requiring autorisation but having no password.

The default behaviour is to return true.

Returns

true if the authorisation in the realm is to be applied.

Reimplemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.

virtual PBoolean PHTTPAuthority::Validate ( const PHTTPRequest &  request, const PString &  authInfo  ) const

pure virtual

Validate the user and password provided by the remote HTTP client for the realm specified by the class instance.

Returns

true if the user and password are authorised in the realm.

Parameters

request	Request information.
authInfo	Authority information string.

Implemented in PHTTPMultiSimpAuth, and PHTTPSimpleAuth.
