Satellite animation related...

[ghansham]

I am working on a web mapping application using open layers. I just liked the way you are animating satellite images. I have following queries:

How it is ensured that browser cache is not full with the images being fetched? And specifically for longer animations where the number of frames may be quite large? And also for large display systems where large amount of data might be fetched from server?

What is the fps of satellite animation?
