+### `connection_timeout`
+
+The connection_timeout parameter is used to disconnect sessions to MaxScale that have been idle for too long. The session timeouts are disabled by default. To enable them, define the timeout in seconds in the service's configuration section.
+
+Example:
+
+```
+[Test Service]
+connection_timeout=300
+```
+
 ## Server
 
 Server sections are used to define the backend database servers that can be formed into a service. A server may be a member of one or more services within MaxScale. Servers are identified by a server name which is the section name in the configuration file. Servers have a type parameter of server, plus address port and protocol parameters.
