One of the new features is URL-based navigation which is useful for creating intranet links or auto-generating email links (such as from workflow systems, etc).

For IIS 6 and earlier, the format is as follows:

http://machine/drm-client/Logon.aspx?
app=<appname>&action=go&ver=<version name>&hier=<hier name>&node=<node name>

Just replace the fields with their appropriate values (URL-encoded of course).

<node name> is optional. If provided it will open the hierarchy and expand directly to the target node. Otherwise the hierarchy is opened to the top node.
