The cache invalidation-upon-write issue is interesting. How large
are the tile caches that Squid holds today? As far as I
understand, there should be three such caches today:
1. Raw background Landsat images.
2. Landsat images with roads drawn.
3. Yellow marks for GPS tracklogs, used by the Java applet.
