Abstract: Future promotions can be tested on a live production website with a preview web application that is separate from a live production web application used by customers. A preview session is established with the preview web application on a live production server responsive to receiving a request to perform a command on the live production server in a preview mode that allows testing of a future promotion. A preview context and a content context are instantiated for the preview session. The preview context indicates a time in the future to use in processing the request on the live production server. The preview web application dispatches the request to the live production web application on the live production server. The second web application processes the request with business logic based, at least in part, on the preview context and the content context.

Abstract: A mechanism to enable context-sensitive attributes which comprise an attribute value and a context value defining the applicability of the attribute value in a computer application. The mechanism is adapted to manipulate the context-sensitive attributes, for example to facilitate creation of attribute values with associated context values, retrieve attribute values associated with a specific context value and search based on attribute values within a context value.
