Using Tcl Variables for Anonymous Sessions

You can use Tcl variables in Region directives to give commands specific information

about a request for anonymous sessions. The commands then can modify the

behavior of the request on the basis of this information.

Table 11-2 lists the variables you can use in Region directives for anonymous

sessions.
