Vulnerability discussion

This policy setting allows you to manage whether applications may be run and files may be downloaded from an IFRAME reference in the HTML of the pages in this zone. Launching of programs in IFRAME must have a level of protection based upon the site being accessed. If you enable this policy setting, applications can run and files can be downloaded from IFRAMEs on the pages in this zone without user intervention. If you disable this setting, users are prevented from running applications and downloading files from IFRAMEs on the pages in this zone.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
