Are you not seeing this at your end?
I did not look into the content of the requests. How would I instrument the code to find out? I was just guessing that they are repeated requests, otherwise they would not keep increasing at a steady rate. I am using the Trackball camera manipulator camera and give the earth.ive a nice fling, so it is repeadily going over the same tiles and not all. The earth.ive only has 12,450 files and there can be many more requests than that in the request queue. > What hardware/OS are you working with?
