[Tilecache] TileCache tile storage questions

[Nguyễn Hoàng Nam]

You should replace default pink tile by a blank tile
Here is my example. The size of folder to storage tiles on disk is only:
 3Gb --> http://112.213.86.71/irrigation
100 Mb --> http://112.213.86.71/dienbien

We also apply this principle for our website: http://imap.com.vn/map
