Hi Jukka,

Thank you very much. I check your post in mailing list. It is very 
interesting.
However, I just wonder that it will work for WCS time tiling which has a 
time attribute in tile polygon. Because I will allow client to request 
both of Spatial and Temporal subset.

I think I may try by replace a tif filename with vrt filename, maybe it 
will work. Any comment is appreciate.
