no cache

I developed a application in flash,

My client wishes not to store this swf file in cache when it displayed in browser.

I suggested embedding this swf in HTML or PHP file or loading this swf file in another swf file so its easy to prevent cache.

But my client say he needs single swf with out any cache stored, is this possible?

Or can is this possible to delete the swf file from cache when we close the application?

Thank you
