To view which pages and objects have been hit while browsing the Internet, select date and time, program user and log type. If mandatory user mode is off use "[EVERYONE]" to see log for every Windows user otherwise you'll get an empty page. You can also fetch log by url and process name (partial strings supported).
To view/modify categories of an URL, select the row from main window data list and click on button Modify or double click the selected row. The view/modify window is divided in 3 parts. The bottom one displays full url requested by the browser. The left one displays in which categories the url and its parts are inserted. On the right one we find the categories list. To add a category to URL/HOST/DOMAIN just select it from the left pane and double click the selected value in the right pane. To remove a category or operate on the whitelist archive double click on category in the left pane. Please keep in mind that you can't remove a category if it's coming from the external service.
