Yes, they are. You can clear the cache by appending a random string to the URL if you need to refresh the cache. I do it by having a text file on my server that the channel looks at on start to see if it needs to get new graphics, depending on the contents of the file. that way I can do a reset but not leave it that way.
Thanks, sounds good. I'm working to an app which has a grid screen with a big number of items, and I want to keep the images cached for a while, to improve speed load. At some point it was looking like the images are cached if I exit and open again the screen, but I wasn't sure.
