I use the html report viewer with a custom reports controller and works great, I'm using a file cache in the default windows temp location ie. C:\WINDOWS\Temp\Html5App. I have noticed a massive amount of files in this folder (all quite small in size but there are so many that the total size is around 4G). I was wondering what the cleanup process is for this cache? should this be handled automatically or is it my responsibility to do the cleanup?
