This property specifies the default amount of time in minutes a Session object will be maintained after the last request associated with the object is made. This can be overridden in script by using the Session.Timeout method.
Note
AspSessionTimeout can be used to tune
your ASP applications. Because Session objects consume some
memory resources, limiting the lifetime of an individual
Session with this property will make your applications more
scalable.
The Web service setting for this property is applicable to all in-process and pooled out-of-process application nodes, at all levels. Metabase settings at the Web server level or lower will be ignored for in-process and pooled out-of-process applications. However, settings at the Web server level or lower will be used if that node is an isolated out-of-process application.
