Arena session variables

The URL to an external website of some portlets may be configured. This is constructed using FreeMarker syntax, with Arena session variables from Arena content included.

Arena session variables provide a low-level interface to the portlet session through the FreeMarker Templating Engine. They enable dynamic portlet configuration.
