This report style displays external content from a publicly available web site published at a URL, which can be specified via the Report tab of the Report Properties window. 

When this report type is run specifically with the Real-Time duration option, the configured web page is continuously refreshed approximately every 1 second. For all other duration options, the web site's content is only downloaded once after the report is opened & run. However, some web sites will contain locally executed logic anyway that automatically keeps the corresponding page's content up-to-date (i.e. is an example of such a web site that shows the time left until the New Year).
