1. A method executed by an interface unit for putting a client on hold, the method comprising:

  • (a) intercepting, by an interface unit, a request from a client to access a requested server;

    (b) determining, by the interface unit, that a response time of the requested server exceeds a threshold by calculating an estimated future response time based on (i) a weighted average of a previous measured response time and a current measured response time, and (ii) a correction factor proportional to the difference between a previously calculated estimated, response time and a corresponding previously measured response time;

    (c) putting the client on-hold, by the interface unit, in response to the determination that the response time exceeds the threshold;

    (d) establishing, by the interface unit, a waiting time for the client; and

    (e) transmitting, by the interface unit, an on-hold request to an on-hold server based upon the waiting time.
