//  An abstract base class containing virtual functions that allow the basic
//  port functionality code to be reused to create another server. These
//  virtual functions create other objects with pure virtual functions which
//  the basic port functionality code invokes thru the v-table.

//  Purpose:    The abstract base class which the server connection monitor
//              thread uses to determine whether server connection should be
//              accepted or rejected as well as creating threads to process
//              client requests.
