Is there a way to easily clear the cache on indigo touch without removing and reinstalling the application?

I've tried removing and adding the server to no avail.

Purpose:
I would like to update images on the webserver without changing their name. That way I can play with a couple of designs, but Touch caches the image and forces me to either rename the image, update the control pages... or i remove the app and reinstall... or is there an easier way to clear the cache?

Thanks! - Jerry

Just force quit Indigo Touch (via the iOS multitasking bar). The cache doesn't persist across application restarts.

Indigo Touch is given a chance to update when it is activated after running in the background by iOS. It is up to Indigo Touch to implement this though.

I am using a variable that has the local time on my server, when that is out of whack with the current time I can find out how stale the data is on my device.

Right now I have to select my server again and it will update (easier then forcing the app to quit).

Can this be a feature request, when Indigo Touch is activating it checks with Indigo to see if there are any updates since it last connected?

This solution did not work. More specifics: I have an IPhone 4. I updated my background.png file. I've tried to restart and recreate the connection. I had to delete the app and redownload it in order for the image to update. The OSX client responded without any issues. It would be a nice feature\bug fix for a future release.

Thanks.
