Abstract: In order to update an installed web package within a manufacturing execution system (MES) the below described steps are performed. A web package update is stored in a packages repository of a file system for the manufacturing execution system. The web package is updated by installing the web package update. At least one user customizable setting is preserved that is applied to the web package prior to the updating and applying the preserved at least one user customizable setting to the web package after the updating of the web package.

Abstract: A method keeps a web session alive for an amount of time allowing to keep a limited amount of data on the Internet information server and manage individually the session timeout characteristics of the web session in the web application. The method automatically refreshes the web pages in the background without any further user interaction. Thereby, a portion of code added effectively creates a hidden postback that keeps alive the session's state. By a class library, the user is enabled at the engineering level to manage a session timeout state and to eliminate a premature timeout thereby eliminating any risk of possible data loss.

Abstract: A method enables the administration of resources (content) in web packages. By automatically adding a prefix to the resource name causing a name conflict, even resources having the same name can be handled when installing a new web package by the virtual file system mapping the resources to which a prefix has been added to the physical content required for the web application.

Abstract: A method and system enable information exchange while switching between a source page and a target page on a drill-down navigation schema, developed with a .NET web application. The method includes providing a smart navigation service, in form of a class library to be configured at page developing time, for managing information for smart navigation between the source page and the target page. The smart navigation service is located, at run-time, in a given user-session and being able, upon-events, to collect, store and provide required smart navigation information from and/or to the web-pages of the given user-session.
