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.

Claims

1. A method for keeping a web session alive in a web application, which comprises the steps of:

providing a software tool that offers at least one software-coded mechanism to keep the web session alive, the software tool having a library containing a first part for managing a specific portion of JAVASCRIPT code to be added to a web page of the web application and a second part for managing responses to requests from a web server that is deriving from a portion of the code added to the web page, the second part being configured as a Hypertext Transfer Protocol (HTTP) handler;

at an engineering level during development of a page of the web application, with a data processing unit executing software with a logical unit, using the library to assign a mechanism selected by a user of the software tool to keep the web session alive to the page of the web application, wherein an assignment adds a respective specific portion of JAVASCRIPT code to the web page of the web application; and

at runtime of the web application, an interaction between the first part and the second part of the library creating a postback running undercover and keeping a web session alive according to parameters determined by the mechanism selected by the user out of the library without performing any additional action of the user on the respective web page.

2. The method according to claim 1, wherein the library is distributed as a dll-file.

3. The method according to claim 1, which further comprises selecting the mechanism from a mechanism group consisting of:

an always on mechanism, an always off mechanism and an activate/deactivate mechanism related to an event.

4. The method according to claim 1, wherein the first part of the library is a class library.

5. The method according to claim 1, wherein the library is distributed as a dll-file and written with a .NET framework.

6. The method according to claim 3, wherein the event is a specific button click.
