Indeed, I have tried that approach too by using the save-state and restore-state hooks but it failed because - a)I think that I might have misunderstood what constitutes the state of the machine (list of urls visited and urls to be visited?) - b) the methods available do not provide a comprehensive interface to the robots state and c) I am dealing with a Domino R5 site that does not exactly lend itself to rational partitioning - it has very unfriendly and seemingly unstructured URLs (therefore not allowing me to devise an adequate segmentation method)
