You can use the following variables in user message templates or administrator message templates:
%USER_NAME%.Name of the current user account on the computer on which the message was generated, in the <device name>\<user alias> format (for example, DESKTOP-123\John.Smith).
%CANONIC_REQUEST_URL%.Address of the blocked web resource.
%RULE%.Name of the rule that blocked the web resource.
%COMPLAIN_EMAIL%.Email address for feedback about web resource blocks. Clicking the email address opens a window in which the user can write a message to the administrator.
%CONTENT_CATEGORY_LIST%.Website category to which the blocked resource belongs (for example, Payment systems).
%TYPE_CATEGORY_LIST%.Category of data type on the blocked web resource (for example, Graphic files).
%CONTINUE_PAGE%.Link to the requested web page (for example, http://www.example.com/pagename.html).
%CONTINUE_SITE%.Link to the website that contains the requested web page (for example, http://www.example.com/).
%CONTINUE_DOMAIN%.Link that can be clicked to gain access to all existing web pages of the domain name. For example, if the address of the blocked web page is http://www.example.com, the %CONTINUE_DOMAIN% variable is replaces with the http://*.example.com link. Clicking this link allows access to all web addresses of the base domain name http://www.example.com/ including subdomains, for example, http://start.example.com/* or http://domain.domain.example.com/*, where the * character stands for any sequence of characters (including an empty string).
