For example, sending a link with an already existing cart number will reuse that number, even though when the attempt is made to purchase the system will recognize that the cart is not unique. There were also some Internet caches which would occasionally keep the cart number.This has nothing to do with whether new [cart]'s will always be unique. You'd have to provide some evidence that you are actually seeing doubles that were not due to bad code. I suppose I could write a Perl script which would spawn lots of child processes and hit a page which returns a new [cart] and match up what was returned with the time requested.John-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747 ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
