Delete Temporary Internet Files in IE 9 from Command Line

There is a way to delete Temporary Internet Files (TIFs) from the command line that works very well for IE 7 & 8:

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8

However, with IE 9, this command does not delete all TIFs. This link explains the problem.

Is there any other (scriptable) command that will work to delete all TIFs under IE 9?
