// @class CPassportHandlerBase | non-template interface class.
// If your codes are being used within a Passport ISAPI Handler, you can
// get access to the current active handler by calling
// CPassportHandlerBase::GetPPHandler(). That saves you from passing
// a global pointer everywhere in your codes.
// Note there are some caveats:
// 1. This works on per-thread scope. If you write an async handler,
// you will have some glitch.
// 2. If you have a handler include chain (in a single processing thread),
// only the top level handler is returned by CPassportHandlerBase::GetPPHandler().
// 3. This method does not work with multiple handler DLLs. In other word,
// child ( sub or include )handlers in a different DLL can NOT get to the
// top level handler.
//
// If you have a CPassportHandlerBase object/pointer you can also use
// GetTopHandler to get access to the first handler within a request.
// This does NOT limit to single thread request and works across multiple
// request handler DLL.
//
// Parent and child handlers can also communicate with each other by calling
// AddPerRequestObj, GetPerRequestObj, RemovePerRequestObj. Note you must
// remove all objects before the destrutor of top handler to avoid memory leak.
