An online store system, which may be implemented as a web site or another type of interactive system, presents context-sensitive information to customers about their prior orders during browsing of an electronic catalog of products. In one embodiment, when a customer accesses a detail page for a particular product, the detail page is supplemented with information, such as status information, about a related order placed by the customer. The related order may be an order for the product represented in the detail page or may be for a related product. Information about related orders may additionally or alternatively be added to other types of pages, such as product category pages and shopping cart pages. In one embodiment, a customer’s related order information is maintained in a cache during the customer’s browsing session, and the cache is updated in real time to reflect actions performed by the customer.
That means: When you are browsing a book at Amazon, it reminds you your previous orders.
