Appl. No.:

09/388829

Inventors:

Kenneth J. Knight - Redmond WA, US
David J. Messner - Redmond WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 15/16

US Classification:

Abstract:

Data is synchronized among multiple web servers, each of which is coupled to a common data server. Each web server retrieves a scheduled activation time from the data server. If the current time is prior to the scheduled activation time, then each web server retrieves updated data from the data server into a staging cache in the web server. At the scheduled activation time, each web server copies data from its staging cache to an active cache in the web server. If a new web server is added or an existing web server is initiated, then data is copied from an active cache in the data server to an active cache in the new or initialized web server. The multiple web servers may be arranged to form a web farm.

Abstract:

Described are product or catalog configuration systems and methods for allowing only valid combinations of attributes to be selected. The invention receives as an input a record set of all the product variants for a given product. Then, dropdowns, or other input portions, for each distinct value per variant dimension are exposed. As the user interacts with the configurator by selecting a variant value, the product record set is filtered by the selections made and the remaining variants are repopulated with only the valid choices for the given variant selections made.
