The default acceptor refers to *dispatch-table* to find a dispatcher
that is willing to return a handler.

To modify this behavior (e.g. have a separate table per acceptor) you need
to subclass ACCEPTOR and set the REQUEST-DISPATCHER slot to an appropriate
function:

   (request-dispatcher :initarg :request-dispatcher
                       :accessor acceptor-request-dispatcher
                       :documentation "A designator for the request
dispatcher function used by this acceptor.  A function which accepts a
REQUEST object and calls a request handler of its choice \(and returns
its return value).  The default is the unexported symbol
LIST-REQUEST-DISPATCHER which works through the list
*DISPATCH-TABLE*.")

  HTH,
