MC40 - Disable page caching of internal browser

I have a partner with the following question on MC40 running GingerBread:

 

We are having issues with compatibility with device.

In some places we use an embedded browser in our app, and the device is caching pages (we want to see how this is managed) because we send dynamic pages back and forth, and this caching is causing all sorts of problems).  How can we resolve this ?
