Default [Q] Accessing streamed browser content from cache?

Hi,

I have searched for this info, to no avail.
I am using RR 3.1.3 on my S2, and I listened to some streamed internet radio.
I'm guessing this would have been downloaded to the browser cache, so I'm wondering if it's possible to locate this downloaded file in the cache, to save and listen to again? I was using the default browser.

Many thanks in advanced for any help on this.
