Tree View
The Tree View displays the entire URL directory of the domain in a tree view. You can choose either one of the URLs to view its violation statistics. Please note that only the URLs with parameters are included in the Tree View directory.
Web site directory
The left panel of the Tree View page shows the directory structure of the website. The / (backslash) indicates the root of the site. You can click a URL in the directory tree, then the violation statistics of this URL will be displayed on the right side of the Tree View page. You can also click a directory, then click Rebuild Directory to rebuild anomaly detection models for all the URLs under the selected directory.
