icm/keep_alive_timeout

Use

This parameter relates to the HTTP1.1 “keep-alive-feature”. This means that if, within this time span, new data arrives over the network from the partner, the ICM attempts to keep the connection open once it has been established. If, for an existing connection, there is no further communication within the specified time period, the ICM terminates the connection. This avoids having to keep establishing and terminating costly network connections.

Value Range and Syntax

You can set values between -1 and 9999999 seconds. If you set the parameter to -1, you switch the timeout fully off. In this case the connection is never closed by the ICM.

It makes no sense to set the value to 0, as the ICM would then close the connection immediately.

Integration

You can override the standard value of the timeout for each service using the icm/server_port_<xx> profile parameter.
