xmla cache issue

Hi,
In mondrian 3.5.0, neither disabling cache nor cache control apis to flush cache seem to be working for xmla connections. Does it use different caching mechanism?
Same thing is working fine for non-xmla (mondrian) connections.

Earlier I had used mondrian 3.3.0 and with that, both disable cache and cache control apis were working fine for both xmla connections and non-xmla connections.

So, my questions is:
How to disable cache for xmla connections?
Can we use cache controls apis for xmla connections:?

Any help is appreciated.

Thanks
Shobha
