Interceptors are a useful technique for extending the basic functionality provided by an Object Request Broker without changing its implementation, nor affecting clients' code. The recently proposed CORBA standard includes a new defnition of portable interceptors. This defnition is very powerful, yet not trivial to use. In this paper we review this defnition, and discuss how it can be applied to provide client side enhancement for caching, load-balancing, flow control (quality of service), and fault-tolerant soft real-time. A recommendation to the OMG for a very minor change in the standard that could greatly simplify its usability is also provided.
