Intralink 10.0: Infoengine Cache

Hello 'Chillers,

Being fairly new to Windchill admin, a few things are still vague to me. (Seems I may be saying that for a few years given the complexity of Windchill admin....)

From my reading, I understand the Tomcat cache to be located in the <tomcat_home>/work folder. Thus, to "delete the Tomcat cache" one simply deletes the contents of the /work folder. (Please correct me if I am wrong.)

But asfor the InfoEngine cache location, I've seen a couple different locations shown in various PTC online documents and PTC/User discussion threads. For example, I've seen:

<windchill_home>/tasks/codebase/<temp>/ptcServlet/

...and...

<winchill_home>/tasks/codebase/com/infoengine

Can anybody tell me with certainty where the InfoEngine cache resides in Windchill/Intralink 10.0 so I can clear/delete it?

TIA!
