Hello,<br><br>Just started with TileCache today. I'm caching images coming from a WMS service that I have no control over. I got it set up with the extent and resolutions I need, edited index.html to point my cache, and it works great. As I was playing with it, it generated some empty tiles - just a white background.<br><br>My first question is, did the remote server return the white images or did it return no image and TileCache made the empty ones. I've used this service for a while and have gotten random errors occasionally that return no image, but I can't remember seeing white images before<br><br>My second question is, now I have cached tiles with no imagery. I assume I can manually delete them, zoom to the area again, and it will load new tiles - hopefully with imagery this time. <br><br>The empty images are only 2KB, so I'm thinking I can use that to determine whether a tile has anything in it. Before I try anything I was wondering if anyone has come up with an automated way to throw out bad tiles? <br><br>Thanks.<br><br>Mike Anderson<br><br /><hr />Express your personality in color!
