/**
 * Used in HTTP/Negotiate, to feed HTTP request info into JGSS as a HttpCaller,
 * so that special actions can be taken, including special callback handler,
 * special useSubjectCredsOnly value.
 *
 * This is an immutable class. It can be instantiated in two styles;
 *
 * 1. Un-schemed: Create at the beginning before the preferred scheme is
 * determined. This object can be fed into AuthenticationHeader to check
 * for the preference.
 *
 * 2. Schemed: With the scheme field filled, can be used in JGSS-API calls.
