Optionally, set ssionTimeout to set an application-specific session time-out value.Set This.name to specify the name of the application.You want to support clustered sessions for example, to support session failover among servers.Įnable session variables in the initialization code of your Application.cfc file or in the cfapplication tag in your Application.cfm file.ĭo the following in the Application.cfc initialization code, below the cfcomponent tag, to enable session variables:.You want to be able to manually terminate a session while maintaining the client identification cookie for use by the Client scope.You want to share session variables between ColdFusion pages and JSP pages or servlets in a single application.You want to maximize session security, particularly if you also use client variables.Therefore, consider using J2EE session management in any of the following cases: Only serializable scopes can be shared across servers. With ColdFusion session management, the Session scope is not serializable. The Session scope is serializable (convertible into a sequence of bytes that can later be fully restored into the original object).You can share session variables between ColdFusion pages and JSP pages or Java servlets that you call from the ColdFusion pages.J2EE session management uses a session-specific session identifier, jsessionid, which is created afresh at the start of each session.J2EE session management provides the following advantages over ColdFusion session management: The ColdFusion server can use either of the following types of session management:ĬoldFusion session management uses the same client identification method as ColdFusion client management. However, you cannot set a time-out value for that is greater than the maximum session time-out value set on the Administrator Memory Variables page.įor detailed information on ending sessions and deleting session variables, see Ending a session in this page. cfc ssionTimeout variable or by using the cfapplication tag sessionTimeout attribute. You can also set the time-out period for session variables inside a specific application (thereby overruling the Administrator default setting) by setting the Application. You can change the default time-out on the Memory Variables page in the Server Settings area in the ColdFusion Administrator. The default time-out for session variables is 20 mins. If the user does not access a page of the application within this time-out period, ColdFusion interprets this as the end of the session and clears any variables associated with that session. Therefore, sessions always terminate after a time-out period of inactivity. In most cases, however, a web application has no way of knowing if a user has finished or is just lingering over a page. A session should end when the user finishes using an application. However, because of the stateless nature of the web, it is not always possible to define a precise point at which a session ends. This logical view of a session begins with the first connection to an application by a client and ends after that client's last connection. As a result, every user of an application has a separate session and has access to a separate set of session variables. Sessions are specific to both the individual user and the application. A session refers to all the connections that a single client makes to a server in the course of viewing any pages associated with a given application.
