For example, the following text is some HTML code that uses %R as a conditional variable to 
check if re-authentication is offered, and uses %r as a regular variable to provide the 
re-authentication URL. 
Any variable included in Table 12-2, “Variables for Customized End-User Notification Pages,” 
on page 244 
can be used as a conditional variable. However, the best variables to use in 
conditional statements are the ones that relate to the client request instead of the server 
response, and the variables that may or may not evaluate to TRUE instead of the variables that 
always evaluate to TRUE. For example, the %t variable (timestamp in Unix seconds plus 
milliseconds) always evaluates to TRUE, so there is little value in making an if-then statement 
based on it.
