ABSTRACT:
The present invention is generally directed to a system and method in which a second application (the “keep-alive function”) sends a ping, message or other signal to a first application to prevent the first application from being timed out (hereinafter, “keep-alive input”). In an embodiment of the invention, the first application is queried as to the appropriate content and format of a timeout period restart message. The keep-alive function may be automatically executed upon the occurrence of a triggering event. The keep-alive function may, periodically or based on a timeout clock related to the first application, check the status of the first application and/or send a keep-alive input.
