![]() ![]() 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.

This way I could test it and do wild things with the data, but the frustration comes as soon as you change your Object stored in your session.īasically this is what you should NOT do:īefore_action :store_path def store_path session ||= if session. I once had the idea to put all this information into an object. That basically means that you have to organize your way of working with sessions. Handling a lot of session data can be pretty confusing, since the session is just a simple storage. That can be pretty handy in many ways, if you think about changing the content of a website based on the session’s information. If you store the version of the sign up form in a session variable, you don’t need to persist this info in your database. Let’s say that you want to show some users a new fancy sign up form and the rest the old form. This is a nice way to enhance the user experience on your page.
