Save cache file to device from videoPlayer/webview

Hi,

I've got a video and audio url that I played using titanium media player. The question I want to know is can I get the video and audio cache file so that I can save it to the device?

Or I can also play it using web view but the question is the same. How can I get the cache file to save it to device?

The video and audio is a remote url.

I'm using 3.4.1 and working on iOS.
