Disable Office Cache Location caching

I generate word document through a web site. Which then prompts the user to either Open / Save / Save As options.

One of our client has set OfficeCacheLocation, explained in the link.

Is there any way to disable this caching through Web [ASP.net ]

or

can we add some tag [XML] in our word document when its generated , so that office does not open / save it to cache ?

Config at client end

IE 9 and Office 2010
