When editing notification HTML files, you can include conditional variables to create if-then statements 
to take different actions depending on the current state.

The table describes the different conditional variable formats. 

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 

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.

You can use variables in the notification HTML files to display specific information to the user. You can 
also turn each variable into a conditional variable to create if-then statements. For more information, see
