[Tilecache] S3 storage and TileCache

[Steven M. Ottens]

Hi all,

I'm looking into using the Amazon S3 support of TileCache. However at  
the moment TileCache is using S3 as storage only and requests the  
tiles from S3 and then sends them to the client, doubling bandwidth  
usage of the server running TileCache. My reason to use S3 is because  
we run out of bandwidth at our setup and we assume Amazon has  
slightly more available :)

I still need tilecache.py because of the sheer amount of layers that  
are available (200 ATM) it is impossible to pretile everything so  
tilecache needs to create tiles if they are not yet available. So  
what I'm looking for is a way to let the client request tiles  
directly from S3 when available and let TileCache create the tile on  
S3 when it is not yet available.

Has anyone tried something like this or has anyone ideas how to do  
such a setup?

Regards,
Steven
