How to configure a session timeout for Grails application?

Question

In one of controllers in my Grails application I'm preserving a parameter value in a session variable like this:

session.myVariable = params.myValue 

After that, I can access the saved value from different controllers/GSP-pages as long as I actively use the app. However, if I don't use my app for a while, even though my browser window is still open, the session variable looses it's value.

Does this happens because the session expires? I was under impression that a session lives until the browser window is still open, but apparently I was wrong.

What should I do to ensure all session variables I define in my Grails app don't expire until the browser is closed? Is there any way to set session timeout manually?

Thank you in advance for your answers!

Another option would be modifying web.xml. Prior you must call

grails install-templates 

Then edit src/templates/war/web.xml and add/modify after servlet-mapping:

<session-config>    <session-timeout>60</session-timeout> </session-config> 

The value of session-timeout uses minutes as unit.
