Has anyone noticed this? It may not be a new thing, but it's the first time I've noticed it. We have a client that uses a few session IDs in product URLS //productDisplay.aspx?id=91 These go from *91 though to *99 I've noticed errors from Googlebot in blocks of 8 each day, scanning URLs that don't have links to them and don't exist, i.e *100, *101, *102 etc Has that been happening for a while?
