This meta tag returns the key value of the current application scope. The tag returns nothing if the currently-executing Tango application file is not part of an application. Managing an application is done through the config.taf application file; see the Application Server Getting Started Guide or Chapter 24 in the User's Guide for details.
For more information on Tango applications and application scope, see "Tango Applications" in Chapter 8 of the User's Guide.
The default value of the userKey configuration variable, which sets the key value for user scope, is:
<@APPKEY><@USERREFERENCE><@CGIPARAM CLIENT_IP>
The presence of <@APPKEY> in the key means that the same variable name can be used in different applications without conflicting.
<@APPNAME>
<@APPPATH>
