Summary :
This SAP note provides guidance for configuring timeout settings for the Internet Communication Manager (ICM) and SAP Web Dispatcher, essential for managing HTTP connections. Key components detailed include setting parameters like icm/conn_timeout and icm/keep_alive_timeout affecting connection setup and maintenance. The document explicates the difference between processing and keepalive timeouts and offers solutions for setting these parameters in the instance profile to optimize system responses and avoid "500 Connection timed out" errors. Available from kernel release 6.40, adjustments in timeout settings assist in handling long-running applications more efficiently.
