Vulnerability discussion

The Cross-Site Scripting (XSS) Filter is designed to prevent users from becoming victims of unintentional information disclosure. This setting controls if the Cross-Site Scripting (XSS) Filter detects and prevents cross-site script injection into websites in this zone. If you enable this policy setting, the XSS Filter will be enabled for sites in this zone, and the XSS Filter will attempt to block cross-site script injections. If you disable this policy setting, the XSS Filter will be disabled for sites in this zone, and Internet Explorer will permit cross-site script injections.

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.
