Windows Internet Explorer fires this event but does not respond to it. The event is intended for use by Browser Helper Objects (BHOs).

The URL parameter returns the exact URL blocked by the browser. Subtle variations in the URL syntax can make this string difficult to parse. Use CreateUri to canonicalize the URL and use the IUri interface to break it into parts.
